The mineral deposits are important for the Russian Arctic. The resources of PGE minerals and gold, nickel and titanium are more than 10% of global significance. Meanwhile, the most arctic territory is out of availability for detail geological and geophysical prospecting due to severe climatic situation and difficult accessibility. The spatial relations of ore deposits and bearing formations of different geodynamic nature at Russia territory show that the geological sequences are of three basic types of geodynamic ...

The drilling and investigation of the Kola superdeep borehole SG-3 for the first time provided direct data on the structure and composition of the ancient continental crust at previously inaccessible depths. Rock density and their anisotropy in elastic properties were used as the main parameters for the formalized description of the borehole SG-3 section and the reference profile on the day surface. The first parameter reflects the rocks' lithology, the second accounts for the intensity of synmetamorphic tectonic ...
