New Data on Minerals RUSSIAN ACADEMY OF SCIENCE FERSMAN MINERALOGICAL MUSEUM volume 42 New Data on Minerals FOUNDED IN 1907 MOSCOW 2007 ISSN 5900395626 New Data on Minerals. volume 42. Мoscow: Аltum Ltd, 2007. 168 pages, 137 photos, and drawings. Editor: Margarita I. Novgorodova, Doctor in Science, Professor. Publication of Fersman Mineralogical Museum of Russian Academy of Science This volume contains articles on new mineral species, among them – Faizievite, Guimarã esite, a rocheritegroup mineral from Brazil, and Ferroskuterudite, arsenide of iron and cobalt from the Norilsk ore field; the description of new finds of recently discovered minerals – Pertsevite and Megacyclite with the structure of the last one; new data on mineralogical assemblages with bituminous matter in pegmatites of the Khibiny massif, on the features of occur- rence of noble metals in ores and oxidized zone of the Onega deposits in South Karelia; the results of studying of Grossular, Vesuvianite and Achtrandite of the Talnakh region; the results of research of transformation of mineral paragenetic assemblages from copper sulfide ores of the Krasnov hydrotermal field; the nomenclature of the Loellingitegroup diarsenides. The paper of the chairman and vicechairman, Subcommittee for Unnamed Minerals, IMA Commission on New Minerals, Nomenclature and Classification, published earlier in Canadian Mineralogist journal, is reproduced here in brief version by request of the Commission in order to introduce the new and approved coding system as widely as possible. "Mineral Museums and Collections" section contains information on mineral collections of Fersman Mineralogical Museum: on art things of masters from the Urals on mineral collections of the Tsesarevichs and of General G.P. Chernik; on the story of one exhibit from the Museum – a black basalt with a golden monogram; and also there is in this section a description of the mineralogical collection of the GeoMuseum, Cologne University, Germany. "Personalities" section includes the article on the exhibition "Jubilees and Their Heroes"; this exhibition was devot- ed to 290 years of Fersman Mineralogical Museum and other jubilees concerning with the Museum. Two more arti- cles are devoted to Professors Alexander A. Godovikov and Georgiy P. Barsanov who had leaded this Museum in different periods. In "Mineralogical Notes" section two articles are published. First, on carbonates in metakimberlite, Zarnitsa pipe, and second, on the twisted filiform magnesian calcite from rocks at Russian platform. The volume is interesting for mineralogists, geochemists, geologists, curators of Natural History museums, and col- lectors. EditorinChief Margarita I.

The central part of the photograph shows the uppermost part of the layered kakortokite series and the overlying transitional kakortokites and aegirine lujavrite on Laksefjeld (680 m), the dark mountain in the left middle ground of the photograph. The cliff facing the lake in the right middle ground shows the kakortokite layers + 4 to + 9. The kakortokite in the cliff on the opposite side of the lake is rich in xenoliths of roof rocks of augite syenite and naujaite making the layering less distinct. On the skyline is the mountain ridge Killavaat (‘the comb’), the highest peak 1216 m, which is made up of Proterozoic granite which was baked and hardened at the contact to the intrusive complex. The lake (987 m) in the foreground is intensely blue and clear because it is practically devoid of life.

  • Summer Polar Adventures Kola Peninsula Washed by the White and the Barents Seas Is Situated Behind the Polar Circle
    +7 (812) 313-43-39 +7 (953) 140-80-89 [email protected] Summer Polar adventures Kola Peninsula washed by the White and the Barents Seas is situated behind the Polar Circle. Since beginning of May and up to the middle of July The Sun is always in the sky and nights are similar to days. Ancient archeological and natural objects of Kola attract by mystic origin. Polar tundra keeps its special beauty of the Northern nature. We will drive off-road to the heart of Khibiny Mountains, meet Saami culture and see the Polar Summer phenomena: The Unsetting Sun. Welcome to the different world to get new impressions and to have the great adventures! Day 1: Murmansk Arrival in Murmansk. Transfer from the airport to the hotel. Overnight. Day 2: Kirovsk - Khibiny Mountains Breakfast and check out. At 08:00am transfer to Kirovsk city for the short city excursion and visiting the Museum of the Apatit Factory with interesting expositions devoted to mining. Then transfer to Tirvas hotel at the foot of Khibiny Mountains where we will have Lunch. After Lunch we get into off-road cars and start our trip to Khibiny mountains. We will drive on the Kukisvumchorr pass and stop at several places to make panoramic photos in mountains. Check-in at a small mountain hotel. Dinner. Evening walk to the waterfall. Then we will hike to a gletcher which never melts to see snow in the middle of Summer. Making photos of The Unsetting Sun in mountain view. Day 3: Saami settlement Breakfast.

  • Introduction to Apatites
    Chapter 1 Introduction to Apatites Petr Ptáček Additional information is available at the end of the chapter http://dx.doi.org/10.5772/62208 Abstract Apatite is the generic name, which was first introduced by German geologist A.G. Werner. These minerals and their synthetic analogs represent a major class of ionic compounds and the most common crystalline form of calcium phosphates, which are of interest of many industrial branches and scientific disciplines. Since, apatite (fluora‐ patite) is the most abundant phosphate mineral, apatite bearing phosphate rocks represents an important source of inorganic phosphorus. First chapter of this book introduces the basic concepts of nomenclature, composition, classification, crystal structure, mineralogy and properties of minerals from the supergroup of apatite. Furthermore, the minerals from the group of apatite and polysomatic apatites are described. Since, the most of the topics mentioned in this chapter will be developed in the following chapters, the key concepts provided in this chapter are important to understood before proceeding further. Keywords: Apatite, Group of Apatite, Polysomatic Apatites, Fluorapatite, Hydroxyla‐ patite, Chlorapatite, Vanadinite The minerals1 [1],[2],[3],[4],[5] from the apatite group2 [6] are classified as hexagonal or pseudo‐ hexagonal monoclinic anhydrous phosphates containing hydroxyl or halogen of the generic formula3: 1Minerals are individual components comprising rocks formed by geological processes classified according to their crystal structure and chemical composition. The total number of minerals accepted by mineralogical community is about 4000. Mineraloids are mineral-like phases including synthetic materials, human-treated substances, and some biological materials, which do not fulfill the criteria for the definition of mineral species [2].

  • Perceptions of the Arctic: Rich Or Scarce, Mass-Scale Or Traditional, Conflict Or Cooperation?
    Calotte Academy 2017 Perceptions of the Arctic: Rich or Scarce, Mass-scale or Traditional, Conflict or Cooperation? Jussi Huotari & Salla Kalliojärvi The 26th Calotte Academy took place in early June 2017. The travelling symposium had its sessions in familiar places: in Inari, Finland, in Kirkenes, Norway and in Apatity, Russia. This year, part of the caravan continued their way to Umeå, Sweden where final sessions of the Calotte Academy 2017 were organized back-to-back with the International Congress of Arctic Social Sciences (ICASS). This year’s academy consisted of twelve full working days, eleven sessions, more than 30 presentations, two excursions, five border crossings and plenty of questions, comments and discussions during and outside the sessions. This would not have been possible without the committed participants, who were ready to allocate their time, were open-minded and willing to share their expertise. More than 30 participants representing thirteen different nationalities formed the group, with approximately half of the group participating for the first time. The multi-national and multidisciplinary background of the group, as well as different levels of experience in Arctic studies, fit very well with the main theme of this year’s academy. After travelling north from Rovaniemi, and entering Sami land and the Sami capital of Finland, Inari, the first working day of Calotte Academy 2017 began on June 1st. Even though June is considered to be one of the summer months in Finland, the weather was not very summery, as it was snowing and temperatures were around 2oC. However, the atmosphere and discussions were warm, while participants debated on the themes of the first two sessions.
