| Реферат: | eng: We have established that the terrigenous deposits of the Haisuin Formation and metamorphic deposits of the Shutkhulai block are similar in geochemical characteristics to the rocks of the Oka Group. The volcanics of the Sarkhoi Group and, to a lesser extent, the crystalline deposits of the Gargan block and rocks of the Dunjugur ophiolite complex served as sourcelands for the studied deposits. The terrigenous deposits of the Oka Group and Haisuin Formation and the pararocks of the Shutkhulai block accumulated in the same sedimentary basin localized on the margin of the Tuva-Mongolian massif in the setting of an island-arc system. © 2011.
