MC method is a computer program developed by K.V. Chudnenko (IGC SB RAS) and O.V. Avchenko (FEGI FEB RAS) for calculation of the mineral modes of rocks by linear-programming technique, where crystal-chemical formulae of the rocks total chemical and mineral compositions are used as input data. This program is differ from the well-known personal computer spreadsheet method MINSQ by a different algorithm, improved accuracy and the additional option “Rock” that enables solving a reverse task - theoretical calculation of rock composition by any arbitrarily assigned mineral modes. The MC method is useful in handling various petrological problems in the fields of metasomatose, metamorphism and magmatism.
Key words: MC, MINSQ, the mode, magmatism, metamorphism, matasomatose, linear-programming technique.
Mineral abbreviations: Qtz – quartz, plag – plagioclase, Kfs – feld spar, Bi – biotite, Hb – amphibole, Wm – muscovite, Gr – garnet, Sph – sphene, Ep – epidote, Opx – orthopyroxene, Apart – apatite, Mgt – magnetite, Ilm – ilmenite, Gbs – gibbsite, Spi – spinel, Chl – chlorite, CC – calcite, Rut – rutile, Anker – ankerite, Sid – siderite, Kaol – kaolin, Py – pyrite, Pirrot – pyrrhotite.

On January 29 th , Far East Geological Institute FEB RAS received short get-to-know visit of foreign delegation consisting of participants of the 21st Annual Meeting of the APPF having been held in Vladivostok, on the Russian Island. The guests
represented science foundations of their countries in Asia-Pacific region: Taiwan, the Philippines, the Republic of Korea, Mongolia, and Indonesia, so the visit could matter very much to the Institute because it has not got any long-term treaties or projects (at the interacademy agreement level) with no one of these countries.

A series of pictures of the erupting Plosky Tolbachek volcano. The photos were taken by the polar-orbiting remote sensing satellites SPOT 5, UK-DMC2 and RADARSAT-1 and received 7-9 December at UniScantm station of ScanEx Research and Development Center in Magadan. Lava streams and ash trains are seen clearly.

On the XV glaciological Symposium "Modern variability of the Earth Cryosphere" (4-7 June 2012, Arkhangelsk Сity)
June 4-7, 2012, in Arkhangelsk was held the XV Glaciological Symposium "Modern variability of the Earth cryosphere" chaired by Academician Kotlyakov V.M. (the official site of the symposium http://glac2012.igras.ru). The organizers of the symposium were glaciological association with the Institute of Geography RAS and the Northern (Arctic) Federal University. The symposium was attended by over than 100 scientists and experts from almost 50 organizations of Russia, Germany, Switzerland, China, Kazakhstan and Uzbekistan. During the symposium were considered issues on various aspects of glaciology (snow cover and glaciers of Arctic, avalanches and mud flows, river and sea ice, ground ice and frazil, mountain glaciers, Antarctic Research).
Seven employees of the avalanche and mudflow processes laboratory of Sakhalin branch FEGI FEB RAS took part in the symposium. They presented five verbal and four poster reports devoted to the research of snow cover and avalanches in the Sakhalin region.

From August 27 to September 5, 2012, Far East Geological Institute, the Far Eastern Branch of the Russian Academy of Sciences, holds the IV Regional Conference of Young Scientists "Modern Problems of Geology, Geochemistry and Ecology of the Russian Far East". Main purpose of the conference is the exchange of new scientific information on current issues of modern geology, hydrogeology and geoecology in the Russian Pacific margin and coordination of the young scientists’ activities in research institutes, universities and geological industrial organizations of the Far East. The aim of this conference is to promote scientific relations, the creation of formal and informal creative teams of young scientists, making them acquaintance with the major Russian scientists. The Far East Geological Institute is a basic research center, conducting fundamental investigations on geology, geochemistry and metallogeny of East Asia and the adjacent Pacific Ocean. Scientific problems to be discussed at the conference are the most important subjects of the hosting institute’s staff researches.
