Institute, University and City

Silver lining at the horizon? This rainbow (Picture below) hovered over our institute building, the Werner-Bau, on November 06. The building is visible enwrapped as if Christo had been there. Those, who regularly visit our institute will be delighted seeing some optically and technically (elevator) very neat new features, but also be surprised about the still rather high fine particle load in the air. We still believe in Father Christ- mas and in completely disturbance-free conditions until Christmas Eve. Then, all laboratories will swing back to full throttle and the very long phase of improvisation will become history. At the same time, new changes emerge – see the outlook on page 21. By the way, the year 2015 was the International Year of Light.

Klaus-Dieter Barbknecht is the new Rector of TU Bergakademie Freiberg. A new rectorate steers our university since October, headed by Prof. Dr. jur. Klaus-Dieter Barbknecht (Picture below). He is being supported by Prof. Dr. Rudolf Kawalla as Vice-Rector for Re- search, Prof. Dr. Silvia Rogler as Vice-Rector for Education and Prof. Dr. Broder Merkel as Vice-Rector for Structure, Strategy and External Relations. Prof. Barbknecht intends to move our university forward with „self- conscious modesty“. We look forward to the collaboration and hope to master the many challenges to the benefit of our university and our institute. Urban legends such as the loss of the university’s autonomy and a forced integration into TU Dresden, analogous to Tharandt, certainly are to be rejected for what they are (such a fat duck as we present would be hard to swallow anayway). Yet, it remains a permanent challenge to steer our little ship safe and sound through all depths and storms. But tact, ambition and performance, as well as enthusiasm for our cause will likely guide us successfully into the future – the next 250 years.

Latinamerican Symposium on GeoParks. The UNESCO-borne and supported idea of Geo- Parks is well established in Germany. For many years it contributes successfully to geotour- ism, to better protection and conservation of geoscientifically valuable areas and to environmental education of the general public. Almost for the same period of time, German colleagues help coordinating the DAAD-supported network of Latinamerican alumni, GOAL. This network regularly organises Lifelong Learning workshops and professional excursions – interchanging the locations between Latinamerica and Germany. Germany hosted the 2014 event with Jörg Matschullat and Klaus Peter Stanek (Geology) as organisers. The focus lay on the still underdeveloped (in Latinamerica) topic GeoParks. The turnout was more than positive and matured thereafter almost by itself. From July 14 to 17, the 1st Latinamerican Symposium on GeoParks took place in Arequipa, Peru under the title “Education in Geosci- ences contributes to sustainable development”. 4 Inst. of Mineralogy – Report 2015

Living on planet Earth. It certainly is a rare event that an entire faculty pulls together as one and jointly produces a book (picture below left). Fortunate boundary conditions, related to our 250th anniversary, made it materially possible. A sophisticated book design complements its content and further supports the impression of unity and pulling together. The title expression of living not just “with” planet Earth, but “on” planet Earth clearly transports the insight that is is us humans, who are being carried by system Earth. An English-language version is underway and will apear some time next year. “Understanding, using and conserving” the Earth forms part 1 of the book with more general information on the workings of our planetary system. The second part po- sitions our Faculty of Geoscience, Geoengineering and Mining in our Resource University. Here, the highly dynamic history of our faculty, our position in the science Fakuttät für Geowissenschaften, community, our ambition as well as future prospects for Geotechnik und Bergbau our alumni are described jointly with profiles of the individual institutes and our magnificent workshop under ) ;i.- the auspices of Erik Börner. Current examples from #'r-. research projects and activities form part 3 of the book AU F DER with examples from every group. This delivers a great introduction into our work and shows the manyfold in- ERDE teraction with both colleagues from other faculties and

A glance into history. It goes without saying that this year will in retrospect, primarily be seen by the university as the 250th anniversary of our alma mater fribergensis. A plethora of events, special exhibits, guest lectures, etc. will take place into 2016 to further commemorate the event (e.g. title page). Beyond this, to almost traditionally look back in decadal incre- ments remains interesting and may provoke some thoughts. In today’s Saxony, the year 1105 saw the settlement of the higher mid-elevation areas by “German farmers”. They Inst. of Mineralogy – Report 2015 5 reached the uppermost parts of the Erzgebirge around the year 1200. A fortress, today Schloss Freudenstein was built in 1175 by Margrave Otto. Ten years later, the Marien church (Freiberg Cathedral) is under construction, and Christiansdorf, the gamete of Freiberg finds its last mentioning in old certificates that report at the same time the Freiberg silver riches. Already in 1225, Freiberg is the largest city (with five churches) and the centre of economic activity of the Meissen region. The Freiberg city council is declared to be responsible for mining law issues in 1255. 1485 is the year of the separation of Saxony into an eastern part with Leipzig and Dresden under the reign of Duke Albrecht (albertinian Saxony) and a western part under Elector Ernst (ernestinian Saxony). Each specific ruler is responsible for the organisation of mining administration. In the same year, the until-today active spa Warmbad near Wolkenstein finds its first mentioning. Hans Röhling is appointed in 1545 to be the first Mining Authority head and Simon Bogner nominated the first Bergvogt – the beginning of a mining administration in albertinian Saxony. Ten years later, the Augsburg treaty corroborates the protestant dominance of electoral Saxony. In 1585 “high ovens” (= blast furnaces) were introduced by Barthel Köhler in the Freiberg smelting industry. The ceasefire agreement of Kötschenbroda ends the 30-year war in Saxony in 1645 already. The country is em- poverished and the mines around Freiberg largely destroyed. Hundred years later (1745) the 2nd Silesian War ends in the battle of Kesselsdorf near Dresden, and Saxony looses its politi- cal dominance to Prussia. 1765: the Bergakademie (Mining Academy) Freiberg is being founded, initially with very few students, most of which from Saxony. As of 1771, more and more foreign students feel attracted or are being sent – their number partly increases above 50% of all students. Abraham Gottlob Werner, namesake of our Institute of Mineralogy, is nominated professor in 1775 (picture at right). With him, the future university de- velops to become an internationally renownded educational center of excellence. In the same year, the “Clausthaler montanistische Lehrstät- te”, later Bergakademie Clausthal, was founded in Clausthal-Zellerfeld, Lower Saxony. The Vienna Congress takes place in 1815: Saxony looses 56 % of its state territory and 42 % of its population to Prussia. In 1835, the Bergakademie Escuela de Minas is founded after the Freiberg role model in Madrid, Spain. Only as of 1845 do our students receive leav- ing certificates. The year 1855 sees the highest number of employees in the Freiberg mines ever – 9.512 people. As of 1875, Freiberg is connected to the northern Bohemian lignite fields through the trainline Nossen–Freiberg–Teplitz, which today runs only until Holzhau. In the same year, the Mining Academy Escola de Minas Ouro Preto is founded in Minas Gerais, Brazil. The right to bestow a doctoral degree (Dr.-Ing.) is given to our Bergakademie first in 1905 – and for the time only in conjunction with the Technical University Dresden. The first rectorate of the mineralogist Prof. Dr. phil. Friedrich Kolbeck ends 1915. As of 1936, the Freiberg mines are being re-opened and take up production. More than 1.000 inmates of the concentration camp Flossenbürg in Bavaria are being forced to labour next to other forced workers in the former Freiberg porcellaine factory. The rectorate of mineral deposit specialist Prof. Dr.-Ing. Friedrich Schumacher ends that year, and the Bergakademie is being subordi- nated to the Reichswissenschaftsministerium in Berlin (the Science Ministry of the Third Reich). 1945 sees a major flux of war refuguees into Freiberg. The people come from East- ern Prussia, Poland and Silesia, and from Dresden. Freiberg surrenders without resistance to the Soviet Army. Teaching at the Bergakademie halts temporarily. Because of his active NSDAP membership, Prof. Dr. phil. Helmut von Philipsborn, responsible for Mineralogy and Lötprobierkunde (an early element detection technique), has to leave the Bergakademie. Our long-term institute director and internationally renownded mineralogist and geochemist Prof. 6 Inst. of Mineralogy – Report 2015

Dr. Hans Jürgen Rösler retires in 1985. Ten years later, petrologist Prof. Dr. Carl Dietrich Werner follows him into retirement.

Institute and Working Groups

Astronomy. The year 2015 stood under a bright and under a dark star. Bright sunlight illuminated the daytime of the 250th anniversary of our university. During the main celebration event in Nikolai church on November 21, the namesake of our house, Abraham Gottlob Werner, was illuminated with honour and humour – he being the person, who brought Freiberg onto the worldmap of science in his days, who founded with geognosy the precursor of modern geoscience and who was a brave producer of daring hypothesis’. He entered the stage „life“, virtually personified by an actor dressed in the festivity attire of a chief mining engineer of the 18th Century. When at the end of the event, everyone stood up to sing the Steigerlied, the miners’s song and Freibergs inofficial hymn, Werner appeared incarnate amongst us (the actor of course) and started the singing. The subsequent miners parade will also remain un- forgetful. As before in the church with the Middlesaxon Philharmonic, an extraordinary chore- ography and the harmonious play of sixteen miners marching bands were quite capable to gave us the shivers once in a while – for joy. Dark on the other hand were the many inhibitions of our work because of the very many renovation works in our institute – still not completely finished shortly before Christmas. Such open-heart surgery is everything but ideal and our university should insist to receive funds to construct a multi-use building in order to improve working conditions for any group under similar boundary conditions. There are limits to improvisation capacity. We nevertheless managed to walk ahead in 2015; our report will inform you about related details.

Biohydrometallurgical Centre (BHMZ). You may call it ambitious when thirteen groups of TU Bergakademie Freiberg try jointly to develop technologies that push frontiers and may become highly relevant for the future of metal mining and winning. The project, generously supported by the Dr.-Erich-Krüger-Foundation, helps us to dare tackle this risk. The next few lines report about the momentary state-of-art in the three sub-projects in our institute: TP 1 (M. Bauer/Prof. T. Seifert). The pre-processed material from the large bulk sample (Wil- helm Stehender Nord, Reiche Zeche) has been characterized mineralogically-petrologically by Mineral Liberation Analysis (MLA). Our focus in Freiberg lies momentarily on trace element geochemistry of the sphalerites from various tunnels and depths by EPMA and LA-ICP-MS (spatial and genetical results on indium mineralisation), jointly with detailed fluid inclusion investigations on quartz and cogenetic sphalerite (Fluid chemistry of the indium mineralisation). In addition, we study indium-rich mineral parageneses from the Hämmerlein, Pöhla district deposit with similar methodologies. TP 4 (J. Heinrich/Prof. G. Heide). Chemical and biological leaching experiments were performed with ore from the Wilhelm Stehender Nord. To inoculate the solutions for the biological leaching steps, bacteria from Reiche Zeche were sampled and cultivated. In parallel, the chemical leaching steps were perfomed to compare the surface changes (etching patterns) of either one of these approaches. In addition, the synthesis of artificial, indium-doted sphalerite was done by toroid press and gas phase transport in collaboration with the first Krüger- Research Group, the Freiberg High Pressure Research Centre and the Institute of Inorganic Chemistry. TP 5 (Christine Pilz, Stephanie Uhlig, Dr. Alexander Plessow, Prof. Jörg Matschullat). In June this year, we finally received the long-awaited material from the large bulk sampling in Reiche Zeche. Next to some smaller batches we could now process the so-called “main batch” with an aliquot weight of 45 kg. The hot summer weeks saw our doctoral students sweat it out in the labs, grind the material to analytical size (<63 µm), homogenise it and fill it into appropriate HDPE-bottles (picture right). Following extensive analytical work, this material will be available Inst. of Mineralogy – Report 2015 7 as In-House reference material TUBAF- KB. These analytical works include an international round-robin test with participants from high-end geo-laboratories in Australia, Brazil, Germany, Norway and the United States of America. The very first BHMZ SummerSchool teaching unit took place at our institute from July 13 to 21. All three groups were involved and had planned a sequence of subsequently interlinked content. The Geochemical-Analytical Labs and its team members designed the first three days. An introduction to geochemistry took the lead, followed by analytical problems and possible pathways to solutions. All three days offered a colourful mix of theoretical and practical training phases. The picture below left shows doctoral students from various BHMZ groups working in our laboratories. While being confronted with mainly un- charted territory, they were highly engaged and motivated and certainly went home with a much better understanding of the challenges and the power of geochemistry at large and in the analysis of very complex geo-materials in particular. To start out with, the working group for Min- eral Resources and Petrology offered a one-day introduction to mineral deposit formation and their characteristics. During a slightly overweighed practical training unit, the participants ob- tained basic knowledge on rock and mineral determination, which had to be trained in situ the next day. That day was spent with an excursion to the Eastern Erzgebirge (visit of the public mine Zinnwald and the Alten- berg mining museum). The picture at right gives an impression from the guided tour in Reiche Zeche during the first section of our SummerSchool teaching unit. During the last two days of the Sum- merSchool, the doctoral students received a short introduction to the field of mineralogy. Using optical microscopy, typical minerals from the Freiberg mining district were determined. An underground excursion into Reiche Zeche (picture above right) demonstrated the experimental facilities for BHMZ, followed by a short-course on X-ray diffractometry. The SummerSchool ended happily with a big barbeque party in our institute garden – offering many tasty self-made salads and grilled specialities.

WG General and Applied Mineralogy Award winner: Dr. Reinhard Kleeberg (picture left) receiving the Pioneer certificate from President Crawford Elliott of the Clay Minerals Society. Orginally proposed by Joe White, the “Pioneer in Clay Science Program” is intended to recognize and honor clay scientists, who have made pioneering contributions to our understanding of clay structures and properties. The program also would provide younger scientists the opportunity to know these early workers on a personal basis and to learn some of the inside stories on some of the concepts and developments that we often take for granted. The program is now a regular component of the annual meeting. The local organiz- ing committee, together with the program committee selects the Early Pioneer and arranges to have the designate participate in the technical program with a lecture.

Guest professorship for Jan-Michael Lange. Jan-Michael Lange is the section head for petrography at the Senckenberg Naturhistorische Sammlungen (SNSD) in Dresden. He guides the laboratories for rock preparation, polarisation microscopy and X-ray fluorescence analytics. His research interests focus on paleogeography and stratigraphy of the Ries impact crater (Bavaria), and particularly its distal ejecta. Additional research activities relate to the analysis of uplift and river history of Cen- tral Europe. In recent years, Jan-Michael also works in interdisciplinary contexts between petrology, archeology and sepulcral culture, respectively. As a custos, he is responsible for the 80,000 rock sample-encompassing petrographic SNSD collections. He is chief editor to various geoscientific journals, e.g. Geologica Saxonica and SDGG as well as member of the DGGV executive board and one of the GMIT editors. Following his education as a geology worker (was a high-level education for practicioners in GDR) Jan-Michael Lange studied geology at Ernst-Moritz-Arndt-University in Greifswald, where he defended his diploma in 1988. A 2-year activity as resource-deposit geologist followed in the Niederlausitz lignite-mining district. In 1990, he received a PhD position at Mar- tin-Luther-University in Halle-Wittenberg. In those years, he became a member of the Ger- man Science Foundation (DFG)-supported graduate school “Formation and Development of the Solar System” at the Institute of Planetology of Münster University. In 1993 Jan-Michael Lange moved on to Friedrich-Schiller-University in Jena, where he was involved in the DFG- project “Multidisciplinary comparative investigations of meteorite populations from polar and subtropical drought areas” with thermogravimetric and mass spectrometric characterisation of meteorites. A year later, he defended his PhD about “Lusatian moldavites and their re- trieval environment”. Still in 1994, Jan-Michael became scientific assistant at Leipzig Univer- sity, where he was paramount to build up and guide the new study line of Geology– Paleontology until 1997. For many years, Jan-Michael Lange supports the Geoscientific Collections of TU Bergakad- emie Freiberg by collaboration in various bodies. Since 2006, he is member of their council and since 2011 member of the selection committee of the Foundation “Mineralogical Collec- tion Germany”. This fruitful collaboration peaked these days in a jointly acquired DFG- framework project for the development and digitalisation of three sub-collections. Building on many years of teaching experience at other universities, Jan-Michael Lange is involved since 2004 – more regularly since 2008 – in teaching at the Institutes of Mineralogy and of Geology at TU Bergakademie Freiberg. He offers the module “Extraterrestrial materials” at the Institute of Mineralogy with two lectures and an excursion since 2008. Until today, Inst. of Mineralogy – Report 2015 9 the student’ response is very positive – not just from those, who need to take it, but also from volunteer participants. In parallel, Jan-Michael Lange continually supports the sedimentological training at the Institute of Geology – with participant numbers of almost 60 students; making it necessary to be repeated at least twice. Jan Michael also takes care of various Bache- lor and Master theses in our faculty. As of October 01, Jan-Michael Lange has been nominated guest professor to honour his long-term engagement and to further deepen the relationship – We in this institute are happy about the welcome reinforcement!

WG Geochemistry and Geoecology Life’s a gas. Well, our work has rather little to do with the rock group T. Rex, which will be little more than a faint memory for most readers. Yet, life as we know it would be impossible without the current composition of our atmosphere (= troposphere). Here, it is of particular interest, how the large element cycles of carbon and nitrogen behave in detail and what the influential processes are (it is amazing how many knowledge gaps there are …). To contribute to such understanding, we per- form increasingly intensive research that focus on soil respiration since 2008. We target all types of soils and quantify fluxes of carbon dioxide, methane and nitrous oxide in de- pendence of soil management, soil chemistry and physics as well as other boundary conditions (the picture at left shows our manual system SEMACH-FG in action). Early in 2016, a review paper will appear in “Chemie der Erde – Geochemistry”. There we compiled and comment on the global understanding (and shortcomings) of this question. In order to be able to help overcome the strong bias towards Europe, as well as to China and the United States of America, we are happy to work as of this December in the Amazon basin, too – jointly with a fine team of Brazilian colleagues from EMBRAPA and the Federal University of Amazonia in Manaus. This project, entitled EcoRespira-Amazon, was made possible through support from CAPES, DAAD and GIZ. Without ambitious students like Thomas Drauschke (picture below left), who could present his results on soil respiration from soils under forest and short rotation forestry in St. Petersburg, we would not stand where we are now. Since September 2015 and until March 2016, three strong ladies from Brazil (Laura Medeiros Braga), Canada (Erin Ritchie) and Slovenia (Špela Preradović Hlede) use their internship with us to run winter respiration experiments at the permanent LfULG monitoring site Hilbersdorf. All three are equipped with stipends and intend to learn the methodology as well as to sniff some of the German air during their stay (picture below right unfortunately without Špela).

Mary Hegeler’s daughter. The mother of Mary Hegeler was the daughter of Julius Weißbach, one of the illuminating Freiberg spirits of the 19th Century. To honour and to commemorate Mary Hegeler, a Post-Doc stipend at TU Bergakademie Freiberg has been named after her. This stipend benefits Dr. Stephanie Hänsel, who intends concluding her post-doctoral thesis (Habilitationsschrift) in 2016. Stephanie’s topics are extreme weather conditions, large-scale weather patterns and climate conditions. She performed very well in these fields following her Master thesis (Diplomarbeit) in Geoecology, and developed methods that are being used by various climate researchers and geoscientists. Such success also helped to recently win a DAAD conference stipend for the 15th Annual Meeting of the Euro- pean Meteorological Society (EMS) in Sofia, Bulgaria (September 7–11). There she, jointly with Dr. Andreas Hoy from our group, who received a similar stipend, are invited to give an entire series of talks. On the occasion of the 250th anniversary of our alma mater fribergensis Stephanie could meet with Mr. Blouke Carus, grandson of Mary Hegeler on November 20. Carus had come from the United States just for the anniversary event.

The international Year of Soils. “When you get right down to the bare facts and weigh all the odds, I myself would say that soil is more valuable than oil or gold” J. Bilyeu. The deep truth beyond this bonmot of a French soil scientist is barely compatible with the current situation of worldwide soil protection and management. Thus it is smart for a resource university to not only think of energetic and mineral resources, but also of the primary ones: Water-Soil-Air, without which and their decent quality our life would be at least drastically inhibited. The situation in Europa is not as bad as many voices like to make believe, however. The GEMAS atlas (Chemistry of Europe’s agricultural soils) by EuroGeoSurveys and edited by Clemens Reimann and colleagues in late 2014 clearly corroborates that argument. Yet something had been forgotten back then: the element nitrogen (N). Soils without (enough) nitrogen cannot support plants and life becomes difficult even for those billions of minute soil organisms. Thanks to our new infrastructure, we were invited to analyse the complete GEMAS sample set for total carbon, nitrogen and sulphur. This was made possible also through support from our chancellor, who enabled buying the latest and most powerful elemental analyser on the market, the EL Cube. The publisher (Schweizerbart) will issue an updated and enhanced atlas some time next year. We are not only thankful for the trust of the GEMAS team in our group, but also to M.Sc. Débora dos Santos Carvalho, cand. gök. Melanie Vierling and our engaged lab-technician Elvira Rüdiger – they all contributed with diligent work to this excellent result.

WG Mineral Resources and Petrology Three new joint research projects were launched this year in our group, all funded by the German Ministry for Education and Research BMBF. They are part of the focal area “r4 – Innovative Technologies for Resource Effiziency – Research to provide strategic resources” within the BMBF framework program “Forschung für nachhaltige Entwicklung (FONA3)”. “DESMEX – Deep electromagnetic sounding for mineral exploration”: this project aims in collaboration with several research instututions and industry partners in Germany at the development of an electromagnetic exploration system using the “Semi-airborne” concept (Pic- ture next page). Sb-(Au-Ag)-veins of the Bergaer Sattel in eastern Thuringia serve as test area. Our task is the investigation of mineralogy, geochronology, genesis and fluid sources of these mineralisations. Investigator: PhD student Lisa Richter, start: 01.06.; Project leader: Thomas Seifert. Inst. of Mineralogy – Report 2015 11

“WISTAMERZ – Prognosis about strategic high technology metals using the Erzge- birge as an example”. The aim of this joint project with science and industry collaboration is a new metallogenetic map of the Erzgebirge. Particularly elements such as germanium (Ge), indium (In) and antimony (Sb) are in the focus of this project. Our group has to fulfil the task of developing a geochemical-mineralogical and geochron- ological database. Investigator: PhD student Tobias Petermann, start: 01.09.; Pro- ject leader: Thomas Seifert. “ResErVar – Resource potential of Varis- cide hydrothermal deposits”. Aims of this joint project are complex models for the geological development and distribution of deposits in the Variscides. These models shall enable a more realistic assessment of the potential of metals such as gallium (Ga), germanium or indium deposits and to find new areas for prospecting and exploration. The working area is, among other deposits, focussing on the Sn-W-Zn-Cu-In (tin-bismuth-zinc-copper-indium) skarn deposit of the Pöhla-Hämmerlein district in the Erzgebirge. The picture at left shows an underground slit sampling pro- cedure in the Hämmerlein mine. The main focus is on the geology and mineralogy of the late Variscan mineralisations, as well as on ore-forming processes of the Sn and In-bearing minerals. Methodologically the project tasks cover a bandwidth from underground mapping and sampling to highly spatially resolved mineral chemical analyses and datings of ore minerals. Investigator: Tilman Jeske, start: 15.09.; Project leaders: Thomas Seifert, Jens Gutzmer.

News from the Laboratories Analytical Geochemistry laboratories (Dr. Alexander Pleßow). The reconstruction in the Werner-Bau that lasted all through the year affected our laboratories stronger than any impact in all years before. Two working accidents of lab technicians at the construction site are to be lamented; one of which led to a minor impact only, while the other one will hopefully not lead to lasting impairment. The unavoidable (under the given boundary conditions) standstills in most of our labs sum up to quite some weeks. At times, all technicians could all day long do nothing but trying their best to clean our equipment over and over again. The practical student lab training could commence this winter term with some delays only and some of the experiments cannot be done this time. Even if by now, late November, two of the labs still do not have heating, and all users need to dress warmly, there are some good news: Still this year, two brand-new digestories (clean benches) are to be installed to replace two older and highly corroded ones. This significant improvement will allow us to obtain a lot lower blind values very soon. This is badly needed for our pressure digesters with the two microwave-assisted systems and classic yet highly up-to-date heating bench system. The latter is brand-new equipment, too, with the enormous advantage that we can select the reaction time and significantly extend the Magnetron-limited duration of the microwaves to be- 12 Inst. of Mineralogy – Report 2015 yond an hour. We are confident to overcome current limitations with the digestion of refracto- ry samples. The downside is that the number of samples to be processed is limited and con- siderably lower as compared to the microwave systems. Thanks to a special financial support by the Dean of our Faculty, our total reflection-X-ray fluorescence spectrometer (TXRF) will be enhanced with a new and more powerful detector. This TXRF machine, which will be moved to another lab once the construction has ended, is characterised by an excellent determination power even with very low sample masses.

Fluid inclusions laboratory (Prof. Thomas Seifert). The Chair of Mineral Resources and Petrology aims at investigating the genesis and development of hydrothermal and magmatic- hydrothermal ore-forming systems respectively. Investigations of fluid inclusions will play a crucial role. To make that possible, the old fluid inclusions lab in the first floor of Brennhausgasse 5 will be completely renovated. New applications-friendly lab furniture, a new lightmicroscope “Olympus BX 50”, a modern heating- cooling table “Linkam TSG 600”, a digital IR-camera “Qimaging Retiga 2000R”, and an analogue IR-camera “Dage LSG-70” with IR-lenses ease the work as of now (picture right). The system allows freezing and heating of fluid inclusions in minerals from -180 to +600°C. The two IR-cameras are paramount here, capable of making light to a wavelength of 2200 nm visible. This system thus allows measuring both transparent and many different opaque minerals (e.g. sphalerite, antimonite, wolframite, pyrite or haematite). The new equipment could be bought through the second Krüger-research school of the Dr. Erich-Krüger-Foundation. The group around Matthias Bauer and Thomas Seifert uses the investigation of fluid inclusions in quartz and sphalerite to gain a better understanding on the genesis and fluid origin of ore veins in the Freiberg mineralisation zone. Lisa Richter works in the “DESMEX” project on fluid inclusions in antimonite and quartz from the Sb-(Au-Ag)- mineralisations of the Bergaer Sattel, eastern Thuringia. Again here, a key aspect lies in a better understanding of formation processes and fluid spources for the mineralisations.

Geometallurgy-Laboratory (Prof. Bernhard Schulz). This lab (also referred to as MLA- lab, for REM-enhanced Mineral Liberation Analysis), saw only work, no changes in 2015. Both REM machines backed a very broad program of research tasks. Studies on REE ores and their dressing product, on Kupferschiefer and on PGM slags stood in methodological focus. An increasing number of analyses were dedicated to research within the Biohydro- metallurgical Centre (BHMZ) of TU Bergakademie Freiberg. Many determinations on materials from fluid trials in Cretaceous limestones were done in collaboration with the University of Stavanger, Norway. Element distribution maps from garnet blasts in mica shists and from amphibole blasts in blue schists and eklogites were paramount for the more petrological questions. More and more vulkanites of all types and proveniences are being analysed, too. The Scanning Electron Microscope (SEM) supports many Bachelor and Master theses. Mrs. Dominique Brising (BSc) supports the lab as a student research assistant. This also helps many researcher guests in our labs, who wish to study their own materials. This included Dr. Yasser Abd El-Rahman (Humboldt fellow Kairo University), MSc Friederike Minz (Technical University Luleå, Sweden), Prof. Dr. Udo Zimmermann, Dr. Naomi Matthews, MSc Mona Minde, MSc Wenxia Wang (all Stavanger University, Norway), Mag. Philipp Lederer (Monta- nuniversität Leoben, Austria), Prof. Hilmar von Eynatten (Göttingen University). The building and reconstruction measures led to two anticipated shutdowns in January and September 2015. Thanks to a mobile emergency energy module in the backyard of our institute, these phases could be successfully covered. The installation of new windows forced a seven-day break in May 2015.

Isotope laboratory (Prof. Marion Tichomirowa). This year, all labs were challenged by the construction activities in the Werner-Bau. Since absolute cleanliness is key to successful work in the isotopic lab, these construction and renovation activities posed a particular challenge. We had to reduce lab-work to the absolute minimum and highly precise U-Pb-dating was basically impossible. This made it the more enjoyable for Marion Tichomirowa that her guest professorship at ETH Zürich lastet until Feb- ruary 28. There, she could successful continue her work on single zircone dating with the U-Pb-method. Early in the year, we had to part from our long-term co-worker and technician Regina Blüthig, and at the end of the year, Klaus Bombach left after decades of engagement for his well-deserved retirement. His position could be advertised and we are still busy selecting an appropriate candidate to fill the niche. Repairs are a constant in a lab, and we were kept pretty busy with that constantly this year. One of the mass spectrometers showed serious instabili- ties and it took a lot of time for Klaus Bombach and Marion Tichomirowa to fix that problem. Since both mass spectrometers are members of an older generation (built in 1990 and 1994), costs for spare parts and repairs in the higher four-digit range ac- cumulated. In November, we had to replace the secondary electron multiplier (SEM) by a new one, since its predecessor simply did not do it any long- er (picture right: SEV for the zircone dating technique; costs: ca. 1.700 €.). A ray of bright sun came into the lab, when the defective air conditioning for the ultraclean air supply could be repaired successfully early this year. Jennifer Schlicke, lab technician, performed a sequence of Sr-isotopic determinations in 2015. This included analyses from archeologial digs at the Petri square in Berlin, with mate- 14 Inst. of Mineralogy – Report 2015 rial from the 11th to 13th Century – seen as the founding time of our capital. The investigations intend to figure out, from which areas those “first settlers” may have migrated in. In parallel, some standards were tested with the Rb-Sr-method. The collaboration with the Saxon State Agency for Environment, Agriculture and Geology (LfULG) continued this year; samples were gained and prepared for zircone dating. Angelika Braun performed the sample preparation steps and the zircone separations.

X-ray diffractometry lab (Dr. Reinhard Kleeberg). With our move into new and newly furnished rooms, significantly better working conditions are available. Completely new elec- trical energy supply eliminates the disturbances in our electronics, the cooling water supply could be stabilized with a more powerful pump, and the stability of the diffractometers enhanced by placing the instruments on very stable plates. The more favourable “cut” of the rooms allows for more space to move, which facilitates the practical student training units. Finally the sinks in the labs supply warm water. The lab development in a nutshell: u moving four diffractometers into the rooms 35/36 in February, re-launch after 14 days of new install- ment and fine-tuning, Control by state technical survey; u refurbish XRD3000TT to 280 mm radius with automatic sample changer in March; u Delivery of MediPix detector for the dif- fractometer Empyrean, successful stability tests; u Improvement of background behaviour of the Empyrean by self-made pre-diaphragm; u Installation and start-up, and first methodological works with the spray-drying machine for sample preparation for quantitative powder diffractometry; u Since June 2015, sample preparation work to pepare the 8th Reynolds Cup in January 2016. Research. The analytical works in the r3-projects (amongst others) could be delivered almost perfectly on time despite the partial inhibition due to construction work.

Shockwave laboratory (Prof. Dr. Gerhard Heide, Dr. Kevin Keller, Thomas Schlothauer). The time-limited permit by the Saxon Mining Authority for the lab endet in July after ca. 200 detonations with explosive masses of about 100 to 2000 g per test. Attested shortcomings could be moved out of the way this year. At the end of 2015, a test blast, using the maximum amount of explosives, will open the path to the final license for its usage. We can very likely take up our research work as of January 2016. Since February, the shockwave lab Freiberg under the guidance of Prof. Heide and Prof. Kroke is part of the new DFG research group 2125 “Structures, properties and reactions of carbonates at high pressures and temperatures” (CarboPaT) with a financial support of 2 x 3 years. The group consists of leading German high-pressure researchers and deals with pressures and temperatures above ca. 50 GPa, similar to a depth of ca. 1200 km in the Earth’ mantle. No opportunity existed to generate such pressures within carbonatic samples at the time of submitting the proposal to the German Science Foundation (DFG) without risk- ing the complete destruction of, e.g. the calcites because of degassing (upper limit currently at ca. 40 GPa). Since pressures above 100 GPa and temperatures above 1500°C are needed for shock wave synthesis of new carbonate structures, a method needed to be developed to increase the current possibilities by a factor of 3. This challenge could be mastered with methods developed in Freiberg (impedance-corrected container, avoidance of Mach effects) and with the support of Russian scientists V. V. Mi- lyawskij and V. V. Yakushev – the “Halide-based methode for fluid rich phases”. Results were presented at the international conference “Interaction of Intense Energy Fluxes with Matter, IIEFM” (picture next page) and published. This allows the Freiberg Shockwave lab, jointly with static methods such as the diamond anvil press, to contribute to researching this interesting field, since we could extend the pressure range to p > 100 GPa. Related works will now be the focal activity of the lab and safeguard its function beyond the support of the Dr. Erich-Krüger-Foundation.

WG Geoscientific Collections Development of the collections. Many addition to our collections could be registered this year. The honorary citizen of our university, Siegfried Flach from Damme in Lower Saxony, donated his extensive collection. This collection encorporates more than 6000 mineral specimen, ore samples and gangue material from Erzgebirge deposits. It is one of the most broad, complete and valuable private collections. Its focus lies on the districts of Freiberg, Marien- berg, Ehrenfriedersdorf, Schlema-Alberoda and Schneeberg. The collector was particularly keen collecting precise information on the location of the finds and the gangue formations and thus built a documentation of Saxon ore mining in its last phase of bloom. He re- searched meticulously in the scientific archives of our university library in Freiberg and main- tained valuable contacts with the Wismut GmbH archive and with former mine geologists and miners. His knowledge is reflected in various publications, e.g. the EMSER HEFT about Schneeberg, the book about 800 years of silver mining in Freiberg, and a mining monogra- phy about Schlema-Alberoda, edited by the LfUG. All of this made his collection attractive to science – both at TU Bergakademie and at the Helmholtz Institute for Resource Technolo- gies in Freiberg. 16 Inst. of Mineralogy – Report 2015

Left: No fear of uranium minerals – Siegfried Flach with a Pechblende specimen from the Erzgebirge. fot: Matthias Reinhardt (Archiv Bode, Mineralienwelt) Siegfried Flach was born on March 24, 1927 in Chemnitz, where he went to school. He successfully finished his apprenticeship in administration in 1944. Training as sailplane pilot followed and then he was drafted by the German airforce. He was taken prisoner of war in May 1945 by British troops and was interned in Ostfriesland. In 1946 he became part of a bomb- blasting unit in Damme near Oldenburg. That place became his new home. Here he did his second apprenticeship as mason and worked for many years on construction sites. He married his spouse Edith in 1950; two sons and a daughter emerged from this partnership. In 1967, Siegfried Flach moved on as construction engineer, working for the city administration of Damme. He retired in March 1990. Next to his collection, which will mostly enrich our Mineralogical and Mineral Deposit collections, another 72 specimens could be acquired for the Mineralogical Collection mainly through exchange. This includes minerals that enhance and complete our Systematic Collection as well as several show specimens that will increase the attractivity of our collections. Two new specimens could be bought with support from the Günter-Heinisch-Foundation. Both were turned over to the Director and the CEO of the Geoscientific Collections during the St. Barbara celebrations of the Verein der Freunde und Förderer der TU Bergakademie Freiberg e.V. on November 28. The first object is a gold nugget (Picture right) from the deposit Nerundinskoje on the Nerun- da River in the Sewero-Baikalski county in the Autonomous Republic Burjatia in Russis (di- mensions: 152 g, 59 x 41 x 19 mm; fot: An- dreas Massanek). So far, a gilded gypsum model of a gold nugget from Russia was on dis- play in our collection, dedicated to Freiberg via Prof. Breithaupt in 1850 by the St. Petersburg mining-Instituts, on the occasion of the Abraham-Gottlob-Werner celebration. The second specimen is an interesting partial pseudomorphosis, where the rare mineral plumbogummite [PbAl3(PO4)2(OH)5·H2O] is grown onto pyromorphite (Pb5[Cl|(PO4)3]) and has partly substituted that mineral (picture right: 20 x 17 cm; fot: Andreas Massanek). This is a new find from the Pb-Zn-deposit Laohu near Gongcheng in the province Guangxi in China. The pyromorphite crystals reach up to 5 cm length and are thus unu- sually large. The attractive colour combination from light blue and green makes the specimen very aes- thetic and a valuable enrichment of our exhibit. Exhange, donations or our own collection activity let the deposit collection grow by another 228 ore samples and the Petrological Collection grew by 92 rock specimen. Two shark egg capsule copies enrich the Paleontological-Stratigraphical Collection. Inst. of Mineralogy – Report 2015 17

Engagement for „terra mineralia“ and for the Mineralogical Collection Germany in Krügerhaus. The success of the permanent exhibits in Freudenstein Castle and in Krüger- haus was safeguarded again in 2015 by co-workers of the Geoscientific Collections. All showcases in the mirror room of the America Hall were cleaned inside out and so were the specimens on closing day in January. Almost 700 hours for terra mineralia and more than 800 hours were invested for “The Mineralogical Collections Germany” by our staff throughout the year. That is necessary to keep the level of the exhibits and to develop it further. Be- cause of this extreme load, the Dr.-Erich-Krüger-Foundation offered half a scientist position, which will hopefully be advertised soon. Nineteen loan agreements came to an end in 2015 for the exhibit “Mineralogical Collection Germany”; a serious challenge for the custos, who needed to find appropriate replacements in parallel. Many talks at collectors’ assemblies, personal talks and participation at fairs attract new benefactors and lenders or convince old lenders to new donations. Thus, the Foundation “Mineralogical Collections Germany” grows continuously: 15 individuals donated specimens; three of them repeatedly. By now, we are proud to name 73 benefactors and 87 lenders (amongst them ten museums). The donated objects alone exceed a material value of 2 million Euros. We exchanged specimens in ten showcases, thus repeated visitors will be able to discover something new with every visit. A phantastic galenite specimen from Neudorf in the Harz Mountains (picture right: 25x20 cm, fot: Andreas Massanek) and supplied to the exhibits by Dr. Erika Krüger deserves special mentioning. This specimen of galenite crystals with a habitus typical for Neudorf in its combination of cube, octaeder and rhombic do- decahedron could be bought at the World’s largest mineral fair in Tucson, USA. Dr. Erika Krüger made it possible this year that the Geoscientific Collections could participate at this important event. Dr. Krüger travelled jointly with the CEO of the collections, Andreas Mas- sanek, to Arizona and opened the fair, jointly with the Head of the fair Peter Megaw, the mayor of Tucson, Jonathan Rothschild, and the president of the show, Paul Harter (picture below; fot: R. Bode, Salzhemmendorf). 18 Inst. of Mineralogy – Report 2015

Thus it became possible after exactly 20 years to partake at this fair – and we explicitly wish to thank Dr. Erika Krüger. Andreas Massanek designed an exhibit with specimens from Germany, representing the Mineralogical Collections Germany in the area reserved for museums. That exhibit attracted a lot of attention, resulting in numerous interviews for Andreas Massanek and Dr. Erika Krüger and in many invitations to special evening events. Parallel to the show, minerals of the Freiberg mineral district and the Geoscientific Collections were represented in the forum through talks given by the custos. It was very interesting and pleas- ing to note that the Freiberg collections and related activities are rather well known in the United States. That we in in Freiberg are responsible for the world’s largest mineralogical exhibit complex, is being acknowledged. It will be one of our main tasks to move these facts into the awareness of both our university and our ministry; a more prominent positioning in marketing of the university and of terra mineralia in particular is needed. The work for and with the Pohl-Ströher-Mineral Foundation triggered an intensified collaboration with Swiss institutions. The Swiss Museum of Natural History in Berne was the focal partner. Dr. Beda Hofmann, custos of the Berne Geoscientific Collections, declared his agreement to engage in the Foundation Council. Another highlight was the organisation and accompaniment of the “Swiss Day” in Freiberg. Using the National Holiday of Switzerland, September 11, the Swiss-German Economy Association e.V. invited, jointly with representatives of the Free State of Saxony under the auspices of the Saxon Ministry of Finance, to „terra mineralia“ in Freudenstein Castle. The many guests were impressed by the collections of Dr. Erika Pohl-Ströher and the related exhibits in Freiberg. Research in the collections. The three DFG projects (HE 3015/5-1, HE 3015/6-1, VO 902/2-1) moved forward fine. Their core activity is the construction of a web-based system to analyse, digitize and visualise a) the collection materials of the historical mineralogical characteristics by Abraham Gottlob Werner, b) the material of the Fossil Fuel Geological Collec- tion and c) the material of the Thin Section Collection at TU Bergakademie Freiberg. The necessary tools had to be developed and the materials gathered and registered. So far, 652 minerals, 249 colour porcellaine plates and 1.176 crystal models from the Characteristics Collection, 640 objects from the Fossil Fuel Collection and about 1.000 thin sections including their record cards could be processed. In a last step, the data will be transferred into the scientific data bank “Aquila” and tested up and down. As of then, the entire collection materials shall be transferred to that data bank and made available to interested scientists online. All works are done jointly with the Senckenberg Naturhistorische Sammlungen in Dresden and Frankfurt. Materials from the Geoscientific Collections were intensively used this year by scientists from TU Bergakademie and from other institutions in Germany and abroad. The Paleontological and the Stratigraphical Collections were included in various research projects. Dr. Sven Sachs, Düsseldorf, specialist for Mesozoic reptiles and Prof. M. Schudack, Berlin, specialist for young Paleozoic carbonaceous alga stayed with us as guest scientists. Other demands on the main collections: 1) pyropissite for Mrs. Hahmann, section Coal/Oil/Gas, TU Bergakademie Freiberg; 2) Upper Cretaceous sponges (Harz Mountains) for Dr. Wisshack, Senckenberg Wilhelmshaven; 3) fossil carbonaceous alga for Prof. Schudack, FU Berlin; 4) Trace fossils for Dr. Niebuhr, Senckenberg Dresden; 5) Tubicaulis solenites for the Muse- um of Natural History, Chemnitz. Ilja Kogan performed manyfold investigations jointly with scientists from other institutions on collections’ material: 1) Saurichthys madagascariensis – morphological investigation, new species description (submitted to Journal of Vertebrate Paleontology) with Dr. Carlo Roma- no, Zürich University; 2) Palaeoniscum freieslebeni – CT-scans and description of the endo- cranium (with Thodoris Argyriou, Zürich University); 3) Saurichthys striolatus – morphological investigation, new species description (with Prof. Andrea Tintori, Milan University); 4) Saurichthys tenuirostris – new species description (with Dr. Ralf Werneburg Museum of Natural History Schleusingen).

Dr. Birgit Gaitzsch used the historically low water level of the Elbe River jointly with colleagues from the Senckenberg Collections of Natural History to work on outcrops that are otherwise basically unaccessible (pictures below).

Left: Fieldwork with colleagues of the Senckenberg Collections Dresden at the Elbe River in Dresden- Briesnitz. The extremely low water level allowed access to upper cretaceous sediments this summer. Right: The strenuous work at 35°C in the shade was compensated with finding various specimen of Inoceramus labiatus More field work by Dr. Birgit Gaitzsch with the Dresden artist Gudrun Brückel: The University Collections “Art + Technology” of Technische University Dresden prepared an exhibit for the winter term 2015/16 on “Sandstone and the Elbe-Labe region as space for nature, culture and encounter” with artistic works by Gudrun Brückel, Jana Morgenstern and Claudia Scheffler as well as Bachelor works from students of architecture and art from Germany and the Czech Republic. Birgit Gaitzsch presented the sandstone material as resist profile. A total of 40 requests for scientific work reached the Geoscientific Collection in Werner-Bau this year; mostly for mineral and mineral deposit materials, and some petrographic samples. Most requests came from our university itself: 12 from the Institute of Mineralogy (TU plus Helmholtz-Institute), 5 from the Institute of Technical Chemistry, 4 from the Institute of Exper- imental Physics, 2 from the Institute of Geology, another 2 from the Interdisciplinary Envi- ronmental Research Centre, 3 from terra mineralia and 1 from the Institute of Ore Dressing Machinery. External requests came among others from the Technical University Dresden and the LfUG in Freiberg. PR work/Special exhibits. The launch of a new volume of the Edition Krügerstiftung deserves mentioning: author Prof. Dr. Gregor Markl, Tübingen University signed the first copies of the first volume on mineral deposits and locations in the Black Forest. A new volume of the Edition Krügerstiftung was presented in Hamburg: Mining and minerals of the Harz Mountains. TU Bergakademie Freiberg is the only university to partake as such trade fair successfully – and uses the opportunity to advertise the city and the study options to the many young people though us. More details can be found in the back part of this report. Obituary for Dr. Ulrich Burchard. One of the most prominent lenders to our exhibit “Miner- alogical Collections Germany”, the mineralogist Dr. Ulrich Burchard from Freising near Munich, died early this year with only 71 years (picture right). 743 wooden crystal models from his private collection can be admired since the opening of Krüger House. His inheritors sig- naled that those models might remain in Freiberg. Dr. Burchard became known for his many publications on historical mineralogical instruments (e.g. microscopes, goniometer, Lötrohrprobierkunde).

Outlook onto 2016 u 2016 will be the International UN Year of Global Understanding. Certainly an excellent opportunity for all of us to communicate our engagement for the understanding of global processes even stronger. u The existence of our Laboratory for Stable Isotopes will come to a standstill early in 2016. Decades of tedious – and most successful – build-up work placed our lab under the guidance of Prof. Joachim Pilot onto the world map. Until the 1990s, colleagues from the western parts of Germany and beyond visited and sought discussion particularly on sulphur isotope methods. Under Prof. Marion Tichomirowa, the lab remained “an address” and one of the few in Germany. Yet the pressure of fixed costs and the loss of personnel made it increasingly difficult to maintain the standard and to keep up the infrastructure. With an experienced alumnus from our institute, Dr. Frank Haubrich, the lab was successfully kept afloat for another few years. Frank now found a full position somewhere else. We wish to thank everyone, who so diligently and successful ran the lab. We miss this infrastructure already, pity the by consequence more narrow hands-on education of our students, and generally that our still relatively broad positioning is cut back yet another bit. u Likely in mid to late January 2016, Katja Horota, Jörg Matschullat and Alexander Pleßow can move back into the Werner-Bau from their exile in Lessing street – then we shall be re- united and complete again. At the same time, there are central plans to move at least parts of our analytical laboratories (isotopic and analytical geochemistry) out of Werner-Bau and into a new attachment to Winkler-Bau. But let us relax – this will take at least another three to five years (more likely five ... ). Inst. of Mineralogy – Report 2015 21 Annex
