Реферат: | eng: We present geochemical data on the composition of manganese ores associated with volcano-sedimentary sequences of the Olkhon and Ikat terranes located at the southern folded margin of the Siberian Platform. The study shows that hydrothermal activity was the major source of manganese supply to the sedimentation basin. The geochemical and isotopic data suggest that the manganiferous sediments were deposited at a distance from the source of hydrothermal activity under the conditions of suppressed terrigenous sedimentation. The lenticular shape and small thickness of the ore bodies suggest that they were deposited in small troughs within a larger deep-water basin.
