Distinguishing of areas for conducting the GDP (GMM)-200 for gold, based on the compilation and analysis of the distribution regularities and forecast maps for the black-shale and epithermal type large-volume gold deposits of the Russian Federation at scale 1:2 500 000

Abstract

The article is devoted to problems of distinguishing the areas for conducting the GDP (GMM)-200 oriented for the black-shale and epithermal type large-volume gold deposits. The approach is based on compilation of the distribution regularity and forecast maps of the Russian Federation at a scale of 1:2 500 000, specialized for these gold deposits, and their analysis. Regional forecast criteria of the gold ore objects and the character of their manifestation over the territory of the Russian Federation are considered. Recommendations are given for setting up the GDP (GMM)-200 programs for map sheets favorable for localization of areas promising for revealing the large-volume black shale and epithermal gold deposits. The forecasted resources of gold and silver of the Far Eastern Federal District and the Arctic zone of the Russian Federation are presented.
