Map of distribution patterns of copper­gold­porphyry deposits in Russia at a scale of 2,500,000 (based on state geological mapping at 1:1 M scale, the 3rd generation)

The content, preparation procedure and predictive­-mineragenic component of the 1:2.5 M Map of distribution patterns of copper-­gold­-porphyry deposits in Russia, first compiled based on summarizing the results of work on compiling sets of State geological maps of the Russian Federation at a scale of 1:1 M, the 3rd generation are discussed. The Map has been prepared from 2017 to 2019 as part of the International project «Deep Structure and Metallogeny of Northern, Central and Eastern Asia». The Map is designed in the form of a GIS project (in ArcGIS 10.2) and includes as thematic “layers” geological, hydrothermal-­metasomatic, geochemical, cosmostructural, geophysical and other criteria, represented on relevant special­-purpose geological maps, scale 1:2.5 M. The Map reflects the location of 297 ore and potentially ore clusters, including 205 clusters in the Russian Far East, promising for the discovery of ore mineralization of the gold­-copper­porphyry type. The article provides recommendations on the direction of further exploration aimed at forecasting gold­copper­porphyry deposits.
Keywords: gold­-copper-­porphyry deposits of Russia, metallogeny, patterns of porphyry distribution.
