... of its origin and evolution. We analyze the available geological data to reconsider the structure and outlines of the Tuva-Mongolia terrane and justify its existence as an independent tectonic unit in the Central Asian belt of Paleozoides. The terrane has a pre-Vendian accretionary basement overlain...
