Abstract: The flyschoid-dominated deep-water sediments especially the "glaciofluvial diamictites" are found to be overlain by the formerly Lugu Formation limestones and volcanic horizons. The pre-Devonian "Gomori Group" shallow metamorphic rock series are mostly redelineated as the Permian strata. A well-exposed Triassic stratigraphic section is constructed. Three formation-scale lithostratigraphic units are established in southern Qiangtang. Tectonically, the "Central Uplift" is interpreted as part of the Lungmuco-Shuanghu tectonic zone. The Shuanghu tectonic mélange zone is separated both at the northern and southern boundaries by giant ductile shear zones. The island-arc volcanic rocks are observed in the Upper Triassic Rola Kangri Group. The important advance has been made for the examination of the NS-trending neotectonics. Abundant larger asphalt veins, heavy oil shows and oil shows are identified in the surveyed areas.
