There are some relevant problems at prospecting-metallogenic analysis of perspective areas: 1. definition of expected formation (mineral) type of mineralization; 2. estimation of the scale of predicted ore mineralization; 3. outlining of the closest analogue from etalon deposits. During formalization this problems can be determined as the problems of pattern recognition, when objects under study described in heterogeneous property space. The conceptual approach to technology support is following: 1. prospecting es...

Mathematical data processing has allowed us to build logical information models based on machine learning (select a lot of informative features (elements), indicating their separating weights and ranges of changes in their values (intervals-indicators), typical for each of the groups of deposits of various formation types). The constructed logical-information models are based on a representative analytical database of 95 gold deposits and gold occurrences in the North-East of Russia. Samples were studied by modern...

The main target of this study is to identify informative features for characterizing the formation types of gold deposits in order to formulate the rules for formation conditions assessing, industrial significance and forecasting of new deposits. Database of ores samples from 95 gold deposits and ore occurrences from the North-East of Russia was collected. Mathematical processing of data has allowed us to compile logical-information models (a set of informative signs (elements), indicating their separating weights...

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 ...
