Anticipating the distribution of gold-­copper­-porphyry­type deposits in volcanic-­plutonic belts of Russia’s eastern regions based on results of compiling sheets of the State Geological Map­1000/3

Volcanic­-plutonic belts in eastern Russia are a natural element of the Pacific folded frame, with which the largest copper-­porphyry deposits are associated. Rather large Malmyzh and Peschanka deposits discovered in recent years in the Russian Far East give ground for high assessment of region’s prospects for copper-­porphyry mineralization. Based on the analysis of regional and local factors of control of gold-­copper-­porphyry mineralization in areas of location of these reference deposits, the prospects of volcanic-­plutonic belts of Russia’s eastern regions for this type of mineralization are estimated. It is emphasized that, along with the nature of intrinsic magmatism of the volcanic­-plutonic belts, the composition and nature of the substrate on which these belts are superimposed are of importance in the distribution of copper­-porphyry deposits of various types. Recommendations are given on the organization of exploratory and medium­scale regional works to discover gold­-copper-­porphyry deposits.
Keywords: volcanic­plutonic belt, gold­copper­porphyry type of deposits, prediction of mineral deposits, State Geological Map­1000/3, deposits Malmyzh and Peschanka, Russian Far East.
