Institute of Mineralogy – Report 2008

Home , Bobritzsch (river), Friedrich Mohs

2008 has been a very special year for us. Following more than four years of intense prepara- tions, terra mineralia opened its gates to the public in October with a week of festivities (see also report 2007). Ever since, the steady stream of visitors from near and afar has already lured more than 50,000 people to the exhibits, and Freiberg is more lively than ever. With the successful filling of the chair of Mineral Resources and Petrology with Dr. Jens Gutzmer (before: University of Johannesburg, RSA), our house is finally complete again and all three groups back to full strength. Shortly before the end of the year, the working group Applied and General Mineralogy received a particular honour: Dr. Kristian Ufer was bestowed with the Hans-Joachim-Martini-Award for his works in the “Development of structural models for the Rietveld quantification of swellable illite/smectite minerals in rocks”. This is the solution of a riddle that has been seen as a non-solvable applied problem for many decades. The additional impetus from these successes is already noticeable. The year was much richer, however, and the following pages report about related events and achievements. We should not neglect the sad sides, though. This mainly includes the death of three reputable professors of our institute who have strongly contributed to shaping our house, its reputation and direc- tion.

Institute, University and City Contemporary issues in and around Freiberg. Rector (Vice-chancellor) Georg Unland was nominated the new Finance Minister of our Free-state of Saxony. Prof. Dr. Bernd Meyer became his elected successor. The neutral Bernd-Erwin Schramm replaced Dr. Uta Rensch, SPD, Freiberg’s first female mayor, after eight years of service. The former county Freiberg grew to the new county of Central Saxony (Mittelsachsen), by merging with the previous counties of Mittweida and Döbeln.

Impressions from the festivities at the inauguration of terra mineralia in Freudenstein castle City and University. After Freudenstein Castle attracts everyone with new charm and beauty, the decision has been made to completely restore the “Castle quarters”. Freiberg won the competition „Ab in die Mitte“, following the motto “Prima-Stadt-Klima” with its plans to Institute of Mineralogy – Report 2008 2 refurbish the Castle Square. Construction has started in parts in late 2008 already and may be completed by 2012. This helps to make city and university grow together even closer. At the same time, a “Science Axis” is being planned from Akademie Street via the Castle Quar- ter and the Castle itself, Brennhausgasse and Silbermann Street, to the University Campus, where a new home for the growing university library and additional lecture halls shall be built.

A look into History. 840 years ago, rich silver findings were made in what is now Freiberg’s historical city (1168). The so-called “Berggeschrei” (like a gold-rush) led to the foundation of the city of Freiberg. Only 50 years later (in 1218) however, Freiberg was named in the re- cords. Exactly 500 years ago (1508), the famous “Tulip Pulpit” by Hans Witten in the Freiberg Cathedral was dedicated to the public. The “Mineralogical Geography of the chursaxon lands” was published by Johann Friedrich Wilhelm von Charpentier in 1778, the base for the later regional geological mapping. 190 years ago (1818), Carl Amandus Kühn started to build up a “geognostic” collection; now the invaluable mineral resource collection of our institute. Friedrich August Breithaupt, Ferdinand Reich, Bernhard von Cotta and his student Carl Hermann Müller became founding members of the German Geological Society (today Deutsche Gesellschaft für Geowissenschaften) in 1848, the year of the first Democ- ratic uprise in Germany. Prof. Dr. Friedrich Leutwein, former rector of the Bergakademie and long-term director of the Institute of Mineralogy in GDR, emigrated to France in 1958. Mining ceased in Freiberg in 1968 with the closure of the last mine and the cavern hydropower station “Dreibrüderschacht”. The same year saw the introduction of the 3rd university reform of GDR. As a consequence, the institutes were disbanded and so-called sections formed. The former Institute of Mineralogy and Mineral Resources was transformed to the working areas Geochemistry and Mineralogy, Mineral Resources and Economic Geology of the section “Earth Sciences”.

On January 17, we witnessed the festive transfer of the castle keys and access to terra mineralia from the mayor Dr. Uta Rensch to rector Prof. Dr. Georg Unland. Just a day later, our faculty bestowed an honorary doctoral degree to Dr. Erika Pohl-Ströher, the generous donor of the terra mineralia collection. The laudatio by the Dean was given by the Vice-Dean Prof. Dr. Jörg Matschullat, and emphasized the scientific value of the collections. terra mineralia opened on October 20, according to plan, and with major festivities. The public response was and is overwhelming. The picture shows a detail from a mala- chite from the Katanga Province, PR Congo, in the Africa Hall of terra mineralia.

Institute and Working Groups We opened a special exhibit on February 1, entitled “Bergkristall”, prepared and designed by our collections’ team (including the opening lectures). Because of its popularity, this exhibit has been extended to June 2009. 17.04. The traditional Mineralogists’ Guild evening featured Jörg Matschullat in the role of Friedrich Mohs (a former professor of mineralogy in Freiberg, 18th century). As we keep to some beautiful traditions, we also sang the Miners song (Steigerlied) at midnight. Despite all prophecies of doom because of the new consecutive studies, it was a marvellous party with very positive resonance from all generations. Our cooperation with Edmonton was continued with a visit of the Dean of Earth and Atmos- pheric Sciences, Prof. Martin Sharp, from February 5 to 7. As of May, we jointly submitted a proposal in the NSERC Programme “CREATE” and with DFG to establish an International Graduate School. Some of our students could participate at field courses in Alberta, a mag- nificent opportunity. Prof. David Lynch, Dean of the Faculty of Engineering visited on April 16, particularly interested in mining engineering and mineral resource issues. Institute of Mineralogy – Report 2008 3

We lost Prof. Dr. Carl-Dietrich Werner, a true mineralogist, on June 2 (see photo at right). He died after enduring a relatively short, but very severe illness. Next to many journal publications, Prof. Werner authored the chapters on “Rock Metamorphosis”, “Diagenesis” and “Metallogeny” in the former reference standard book “Entwicklungsgeschichte der Erde”, published by VEB F.A. Brockhaus in Leipzig. After German re-unification, he was a key person to establish contacts with the West German colleagues and rapidly participated, e.g., in IGCP programmes. We miss an honest colleague who kept active, engaged, and productive in the field long after his retirement. A “true” obituary will be published in 2009 in one of the next issues of the Geohistorische Blätter: http://www.geohistorische-blaetter.de/. 29.06. – 5.07. and 30.09. – 6.10. Following a visit from high-ranking representatives of the University of Namibia (UNAM) in Freiberg, a delegation, representing our geoscience institutes, visited Namibia twice. The idea is to jointly build up a M.Sc. programme in the geosciences, supported by DAAD. We developed a concept to implement the program jointly with our geophysicists and geologists, hoping that this partnership may flourish. September. Decision made for construction activities in Brennhausgasse 5 and 14 (see outlook, below). On November 15, we lost our esteemed colleague and mentor, Professor Dr. Ludwig Baumann (picture left), following a long period of illness. Professor Baumann served from 1966 to 1993 as a chair for Mineral Resources and Metallogeny at our institute. He is first author of key literature (all in German) such as Baumann L, Tischendorf G (1976) Introduction to metallogeny and minerogeny; Baumann L, Nikolskij I, Wolf M (1979, 1982) Introduction to mineral resource geology and exploration; Baumann, L, Kuschka, E, Seifert, T (2000) Mineral resources of the Erzgebirge. From 1974 to 1989, Professor Baumann served as the Chief Editor of the international series “Topical Reports of IAGOD – Problems of Paragenesis” that appeared under the umbrella of the Freiberger Forschungshefte. This publication was to be an important contribution against the international isolation of mineral resource geology in GDR. We will honour Professor Baumann and remember his engagement, partly under very difficult conditions, for mineral resource geology in GDR, in the re-united Germany, and on an international scale. Professor Dr. Ludwig Pfeiffer (picture right) died on December 21, after a very long struggle against a terminal disease. Prof. Pfeiffer was a petrologist and served for many years in our institute. Many know his textbook: Pfeiffer L, Kurze M, Mathe G (1981) Introduction to Petrology (2nd ed. 1985); Akademie Verlag Berlin (in German). The Meissen Massif and the Tertiary volcanism in Saxony and Bohemia were among the focal points of his activities. The fine relations between Freiberg and the Charles University in Prague are certainly and strongly related to his activities.

Applied and General Mineralogy 8.—18.03. Gerhard Heide and Wolfgang Voigt (Department of Chemistry) visited the Uni- versity of Potosí, Bolivia, with which our institute maintains a long-standing collaboration ever since Abraham Gottlob Werner (18th century). The foundation of a Solar Research Institute and a lithium enrichment plant were prepared. April. Dr. Reinhard Kleeberg and Dr. Kristian Ufer received the prestigious Reynolds-Cup in quantitative mineral analysis (2. rank) and two of Dr. Kleeberg’s students were in the top five positions worldwide. See http://www.clays.org/reynoldscup/Past_Competition.html. 12.—18.05. Dr. Kleeberg ran the Alberta Powder Diffraction Workshop, UoA in Edmonton; See http://www.cins.ca/apdw/speakers.html. Institute of Mineralogy – Report 2008 4

15.—27.05. Prof. Dr. Jens Götze served as a visiting professor at the University of Krasnojarsk, Russia. August. As invited speaker at the IGC 2008 in Oslo, Jens Götze talked on “Chemistry, tex- tures and physical properties of quartz – geological interpretation and technical application”. 19.—22.09. Workshop "Powder diffraction software" and keynote lecture by Reinhard Klee- berg: “State-of-the-art and trends in quantitative phase analysis of geological and raw materials” at the EPDIC XI Warszawa, Poland. Lomonossow-Stipends are based on a joint programme by DAAD and the Russian Fond for Basic Research. Stipends are given for research stays of different length to students, doctor- ral students and senior scientists, working at German institutions. The timing is between several weeks and half a year. In 2008, the group was enriched with two bursaries: • Dr. Talovina from the Mining Institute St. Petersburg worked with us from September to December in the XRD laboratory and at the scanning electron microscope. She re- searches the mineralogical composition of silicic nickel deposits in the Ural – a major challenge in particular due to the unusual Ni-rich phyllosilicates (“clay minerals”). Even Reinhard Kleeberg could not answer all of the related questions. • Mrs. Komashchenko from the Academy of Geological Prospecting in Moscow works with us from September 2008 to March 2009. (Both the Mining Institute and the Academy are partner universities of TU Bergakademie Freiberg). Mrs. Komashchenko does her doctoral thesis on mineralogical investigations of precious berylls with a focus on the cathode luminescence of beryll. In addition to the large sample collection in Moscow (ca. 60 samples), we could make good use of our own mineralogical collection materials. More visiting scientists, supported by DAAD in the XRD laboratory were: E. Balladares from the University of Concepcion, Chile, and I. Talovina from the Mining Institute in St. Peters- burg. Direct external industry services amounted to 42 reports. We could modernize (new controller and software) the Differential Thermoanalysis TG-DTA 92 (Setaram) with funds from Gerhard Heide’s appointment, and buy a new workstation 8 core XEON for the XRD lab through a contract with the BGR (German Geological Survey).

Geochemistry and Geoecology Two highlights stand for the year 2008: the expedition to Northeastern Brazil (BraSol-2010; a few impressions in the pictures below; http://tu-freiberg.de/ioez/brasol/), the obtained samples of which will keep us busy for many months to come, and the successful acquisition of the joint BMBF research project REGKLAM (http://www.regklam.de). Another reason to ce- lebrate is the return of Dr. Frank Zimmermann to our group – thanks to our rectorate. At the same time, Prof. Dr. Werner Klemm had to retire officially. Fortunately, he does not take this too serious and we are happy to see him contributing to our team in teaching, student men- toring and research – the latter now primarily dedicated to building stone decay.

Jörg Matschullat participated for the university, the faculty and our institute at the DAAD-GATE education fair in southern Brazil. He tries to attract more Brazilian students to Freiberg in São Paulo, Caxias do Sul, Porto Alegre, Curitiba, Florianópolis und Campinas. The resonance was rather enthusiastic.

April. Our doctoral student Claudia Heidel, was endowed with a travel stipend from VNG AG to St. Petersburg. She received the award for the best presentation. May. The 6th Annaberg Climate Days attracted record numbers of participants to the beautiful mining town. The conference focussed on the important topic of insecurities (methodo- logical, with scenarios and models: http://www.ioez.tu-freiberg.de/veranstaltungen/veranstaltungen.html). May/June. Prof. Dr. Edeltrauda Helios-Rybicka from AGH Cracow, our partner Mining Acad- emy in Poland, came as a visiting Humboldt fellow to prepare a joint project and a new proposal. July/August. Jörg Matschullat travelled with twelve Freiberg Geoecology students to North- eastern Brazil (see above). The group met with one more Freiberg student who studies in Campinas (UNICAMP), and with Brazilian colleagues and students from two universities (UFRN, Natal, and UFV, Viçosa). Within five weeks of field work, 1.8 Mio. km2 were sampled for soil geochemical investigations. Eleven Federal States were covered, 17.000 km travelled, 555 boreholes drilled by hand, 150 composite samples taken, prepared and split in aliquots for our Brazilian colleagues, and we managed to get the rest home safely. The ana- lytical work and data evaluation will keep us busy for quite some time. Results and further information may be obtained from http://tu-freiberg.de/ioez/brasol/index.html. September. Our sub-projects in the BMBF research project REGKLAM took up work. This complex project intends to develop an adaptation strategy for the larger metropolitan Dres- den area to regional climate change (www.regklam.de). It is the first supported project in Germany from a total of seven within the larger framework of klima2. We start with wet-only precipitation sampling (chemistry; the picture at right shows the commercial Eigenbrodt sampler next to our own machine); with aerosol particle filter determinations from Ghent samplers, and the installation of a remote control connection between our stations Oberbärenburg and Freiberg, as well as the continual monitoring of meteorological, micrometeorological, and atmospheric chemistry parameters at both Freiberg and Oberbärenburg. For our teaching duties, we integrated the newly designed lectures from the focal area “At- mospheric Research” for the future M.Sc. in Geoecology into the OPAL system (a web- based educational tool set), newly compiled the lecture series “Atmospheric Chemistry”. October 2008 to March 2009. The third Lomonossow stipend at our institute went to Dr. Ya- na Panteleeva from St. Petersburg. Yana works on a multi-element, multi-media study of the impact of mining and smelting operation in the Kostomuksha area, Karelia, on the complex environmental situation – a prerequisite for the development of sustainable mining techniques. All year. The central aim of the EU Water Framework Directive (WFD) is a good ecological situation of surface waters in the European Union, to be reached by 2016. Norm ex- ceedances are foreseeable for several trace elements in surface waters and their sediments within the Saxon mountains; the reason being geogenic enrichments of such components. The research project thus aims at a further differentiation of those geogenic background values for the above stated compartments on the scale of the surface water body. Thus, we expand the existing knowledge on the individual characteristics of partial catchments in the Erzgebirge and Vogtland area, studying average trace element concentrations in river sediments and comparing these with the element status of related soils and rocks. Three partial catchments were delineated for more intense research in cooperation with the State Authori- ties: i) the upper reaches of the Freiberg Mulde from the Czech German border to the influx of the Bobritzsch river, ii) the upper reaches of the Zwickau Mulde from its sources to the influx of the Schwarzwasser, and iii) the Schwarzwasser catchment. In each of the catchments, 1 sample was taken per 10 km2 (WK). Institute of Mineralogy – Report 2008 6

All year. Continuation of the DFG project “Experimental investigations on sulphur and oxygen contributions to sulphide oxidation” with the doctoral student Claudia Heidel. Many experiments were performed and the evaluation has started. First manuscripts have been writ- ten and partly submitted to international refereed journals (annex). Claudia Heidel presented her results at two international conferences: 1) International Conference in St. Petersburg “Topical issues of the rational use of natural resources”. She received the 2nd price for her presentation in the area “Geology”; 2) International JESIUM (Joint European Stable Isotope User Meeting) in France with “The isotopic composition of sulphates formed by pyrite oxidation”. In August, we sent the intermediate report to the DFG, jointly with the proposal for ex- tending the project for another year. Jörg Matschullat became a member of the DIN commission NA 134-04-02-19 UA (aerosol sampling; since late 2007). A proposal sketch was submitted to DAAD and AA for the ARID International Climate Net- work. A first decision is expected in January 2009.

Mineral Resources and Petrology Next to numerous activities, to be named below, the filling of the vacant chair with Prof. Dr. Jens Gutzmer from Johannesburg certainly was a highlight for the group and the entire institute. This relates to restructuring and new directions of the group which will certainly contrib- ute to an even bigger impact of the institute in the future. 07.04.—01.05. Dr. Axel Renno is invited visiting scientist at the University of Krasnojarsk, Russia. He tought physico-chemical mineralogy, microscopy and petrology). 15.—18.05. Co-organisation of the Third VENTS Field workshop by Prof. Christoph Breitkreuz in Freiberg (http://www.geo.tu-freiberg.de/dynamo/VENTS.htm). Katarzyna Liso- wiec from the University of Warszawa stayed with us for this event, and again from 9. to 16.10. as DAAD bursary – a joint Master’s thesis with Prof. Ewa Słaby (AR). 12. and 13.06. The traditional Freiberg Mineral Resources Colloquium took place under the motto “Metallogenetic Models and Exploration Strategies for Mineral Deposits” during the 59th Berg- und Hüttenmännischen Tag “Ores, Industry minerals, Salt, Coal”. The event tur- ned out to be very successful with more than 80 participants from mining and exploration companies, state institutions, and universities from Germany, Norway, Austria, Poland, the Russian Federation, and the United States of America. Dr. Thomas Seifert and Prof. Dr. Nor- bert Volkmann organised the event jointly, and 15 companies, institutions and scientific organisations, national and international, sponsored the event (http://www.mineral.tu- freiberg.de/econgeology/img/BHT2008-Abstracts.pdf). 20.—31.07. Geological-petrographical Field training Eastern Alps with 15 Bachelor of Geo- sciences participants, headed by Prof. Dr. Bernhard Schulz: Ötztal, Zillertal, and Deferegger Alps. 15.9.—05.10. Three-week field trip to the Republic of Armenia with 19 Geo-students; picture at right (AR) 21.09.—03.10. Dr. Thomas Seifert was invited as visiting scientist by the University of Krasnojarsk, Russia, and lectured: Ore-forming proc- esses, Mineral Resources, Regional Metallogeny, and a practical on ore microscopy. 20.—28.10. Prof. Dr. Holly Stein (Colorado State University, Norwegian Geological Survey and Humboldt fellow at the GFZ Potsdam) and Prof. Dr. Judith Hannah (Colorado State Uni- versity) visited the group to select samples with Thomas Seifert for a joint project on Re-Os dating of W-poly-metal, Sn-poly-metal, and Bi-Co-Ni-Ag mineralisation’s from deposits in the Erzgebirge – and to officially participate at the official opening of terra mineralia. November and December. Cooperation project with Prof. Ziying Li (President Beijing Re- search Institute of Uranium Geology): visit of Prof. Li in Freiberg from 30.11.—07.12. (AR, Institute of Mineralogy – Report 2008 7

TS), and a subsequent visit of Thomas Seifert in Beijing and to post-magmatic W and U- deposits in the Jiangxi Province, PR China.

The '7th Freiberg Short Course in Economic Geology' became a major success. It was organized by Prof. Dr. Jens Gutzmer and Dr. Thomas Seifert under the topic “Broken Hill-type Zn-Pb-Ag deposits”. Prof. Ian Plimer, University of Adelaide presented the course, supported by Prof. Rodney Allen (University of Lulea, Sweden), and Dr. Craig McClung (TeckCominco, Namibia). A total of 80 participants from nine countries represented different research organisations and the mining and exploration industry.

Geoscientific Collections The year 2008 beyond doubt stood under the auspices of terra mineralia. The team contributed to planning for the display cabinets, the safety and locking techniques, and the furnish- ing of offices and functional rooms. A large number of student and scientific helpers as well as numerous volunteers were coached during the collection documentation and exhibit reali- zation. Many print media, including for the book “Highlights from the World of Minerals” had to be prepared and supported. Last, but not least, the team had major tasks to fulfil in the organisation of the festivities from the symbolic transfer of the castle keys on January 17, and the following two Days of the Open Door (18./19.01) with numerous guided tours. The team transferred the collections into the castle depot (April to August), and made the design concept in four of five large halls a reality (July to October). At the opening finally (20. to 26.10) every hand and head was basically involved 24 hours a day. As every year, additional special exhibits were organized and displayed. A total of 385 specimens were given to different users (mainly university institutes – see annex). The large thin-section documentation (15,000 pieces) could be continued. The collection premises in the Humboldt-Building (Geology) and the Petrological Collections in the Werner-Building (Mineralogy) were re-designed. Lighting was changed in the Mineral Resource and the Petrological Collections. As usual, intense visitor and trainee coaching kept us busy. Parts of the Mineral Resources stockpile collections were re-organized. Next to the collaboration with the University of Hamburg on a type mineral specimen catalogue, an extensive collaboration took place with the Museum of Natural History in Görlitz, Saxony. For more details, see the annex. Institute of Mineralogy – Report 2008 8

Outlook We expect a major renovation of the rock and mineral preparatory laboratories in Brenn- hausgasse 5, to allow for a better separation between ores and non-ores, reduce the contamination risks involved, and to generate better working conditions at large (lighting, clean- ing, etc). The sample preparation techniques shall be further improved, building on our related activities in 2008. We also hope to find a fine successor to our long-term an dedicated lab-technician Beate Düsing, who has to retire soon (all of us). Within the BMBF joint project REGKLAM, we expect to launch the Berner Impactor at the Zinnwald Meteorologial Station (Erzgebirge), the start of the PARTISOL measurements, a further development of the Relaxed Eddy-Accumulation method to describe the fluxes of reactive N-species, aerosol measurements in dependence of meteorological conditions, the installation of the new Vaisala visible range device in Oberbärenburg, and its coupling with the new automated fog samplers (Geochemistry and Geoecology group). We hope to be able to install a new scanning electron microscope with integrated image analysis to start up the geometallurgical studies. A related proposal has been submitted via the Faculty of Geosciences, Geotechnics and Mining. A joint PhD program with the Depart- ment of Geology, University of Johannesburg, Republic of South Africa is another aim to enhance the expertise in Geometallurgy (Mineral Resources and Petrology team). Terra mineralia. The opening of the fifth exposition hall (Asia) is planned for 27.-29.3.2009. Collections in the Institute. As of 5.01.2009, we offer new opening hours: Mo – Th: 9—12 hrs and 13—16 hrs. Institute of Mineralogy – Report 2008 9

Some other activities Since 2008, a technical bi-lingual dictionary and translation programme for Portuguese-German- Portuguese is available with Beolingus http://dict.tu-chemnitz.de/. It finds a lot of friends and is one of the very few opportunities to encounter a profound and quality controlled translation aid for the (Brazil- ian) Portuguese language. This permanent project at the same time serves as an official German- Brazilian contribution to the International Year of Planet Earth (IYPE), similar to BraSol-2010 (see above): http://www.yearofplanetearth.org/. Public Relations: diverse staff members were engaged as usual during the year for • Special teaching unit on Geosciences at Gymnasium Nossen, emphasizing the collections (UK) • Jörg Matschullat gives and invited keynote lecture on “New challenges for the city in the 21st century” within the „Ab in die Mitte! Die City-Offensive Sachsen“ at IHK Chemnitz on 27.2. • Days of the Open Doors, January 10 and June 07, 2008 • Diverse information for citizens (e.g., on particle characterisation, Mr. Wolter from Kiel; Soil reaction under climate change, Mr. Waurick from Oderwitz, etc.) • Guided tours for students from other universities (e.g., in May for the partner university Os- trava, CZ) • Regular referee for the Czech Academy of Sciences (JM) November. Visit from Prof. Dr. Toki Sato (Univ. of Akita, Japan) with a well-attended lecture on the use of nano-plankton as a proxy for climate change in the system ocean.
