摘要

In the eastern part of the Aldansky shield, o the territory of volcanic and sedimentary basins of Proterozoic age, many deposits and ore occurrences of Au, Ag, Mo, U, V, Ni, Co, Ba and Th are revealed. Petrographic, geochemical and fluid inclusion study indicate their low temperature (epithermal) genesis. It is supposed that these ores were formed in the grenville metallogenic epoch (Upper Proterozoic).
