| Abstract: | The relationship between noble metal mineralization and carbonaceous rocks (black shales and brown coals) is considered. We have confirmed the previous conclusions of multistage syn- and epimetamorphic formation of gold-bearing deposits in black shales and syn- and epigenetic accumulation of noble metals in brown coals. The gold and PGE in the brown coals of the Verkhnii Amur region and Primorye were presumably derived by disintegration of adjacent ore sources in the Cenozoic. Addition studies and sampling are required at the coal and graphite objects of the Russian Far East to solve this problem. |
