Tethys Ocean formation and evolvement poses one of the important fundamental geological issues in studies concerning the Tibetan Plateau Integrating the field work, data analysis, previous studies, and particularly with the 1∶250 000 regional geology data, in Bayankala tectonic belt during Permian-Triassic, including the normal stratum, lithofacies character and tectonic-paleogeography, we discussed the tectonic evolvement in order to improve the research level of the Tethys ocean development in Tibetan Plateau and Rodinia continent formation. The Permian-Neogene’s stratum appears in the main body of Bayankala tectonic belt, characterized by disappearing portion of Triassic stratum before Permian. It evolved from ocean environment to continent environment during Permian-Triassic after collision; orogenesis and the blue water vanish, as the north part of main double ocean region contrasting with the south Longmu lake-Shuanghu ocean of Palaeo Tethys ocean lying between Tarim-China-Korea plate and south big continent (Gangwana continent).
