Laboratory of geology and mineralogy of precious metals carries out studies of minerageny of precious metals from the Verkhoyansk-Kolyma folded area and adjacent structures of the East Siberian platform, ore-magmatic systems and factors if their productivity, including geologic-genetic and GIS prerequisites of presence of complex precious metal mineralization at the East of Yakutia (as basis of increasing precious and non-ferrous metal resources; Multicomponent precious metal deposits of the Eastern Yakutia, regularities of occurrence in connection with the history of the Verkhoyansk-Kolyma folded area evolution, structural, mineralogic, lithologic-geochemical and physical-chemical features of of the formation; regularities of occurrence and relationship of supposed primary sources of placer gold at the East Siberian platform.
Main research areas and types of conducted works
- Geologic data bases and GIS-technologies for their visualization based on geographic, geologic and geophysical cartography;
- Drawing geologic maps of promising ore-magmatic clusters, based on detailed space photographs;
- Different natural event monitoring, based on Landsat-8 satellite images;
- Drawing maps of temperature fields, based on Landsat-8 data conversion in temperature values;
- Preparation and use of digital model of Yakutia relief in order to identify previously unknown magmatic bodies, evaluate flooding of flood hazard areas to minimize property damage and etc.;
