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 hybrid expert systems are the most effective for solution of geological problems, because their knowledge base includes not only knowledge of experts, but also the regularities received as a result of the analysis of available databases. The prediction problem was the first among the geological problems for which the expert system technology was used for solution. According to the principle of consecutive detailing the main prediction-metallogenic taksons of the researched objects are needed to consider: metal...

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 ...
