Аннотация: The geologic positions and geochemical and isotope parameters of the Ordovician-early Silurian and Early-Middle Devonian continuous volcanic series of the Minusa basin and its mountainous framing are compared. Both series are composed mostly of moderately alkaline rocks with variations in SiO2 contents from 45 to 77 wt.%. The OrdovПоказать полностьюician-early Silurian series differs from the Early-Middle Devonian one in lower contents of TiO2 (
