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...

Regularities in the distribution and forma tion mechanism of gi ant Cu-Au-porphyry deposits have been discussed by many authors. Most recent works are dedicated to the problem of their formation. The deposits of Macedonia discussed in this communication usually contain up to 150 000 t of copper with the Buchim deposits likely being the smallest in the world am ong similar recently mined deposits. The long- term economically profitable development of the latter refutes the traditional opinion that only Cu-Au-porphy...
