Abstract

Abstract

The Wuling orogeny made a significant influence in eastern Guizhou and its adjacent regions, as reflected by the appearance of disconformities between middle and upper Proterozoic. It took its most profound expression in northern section of the Fanjing Mountain of Guizhou Province, Dayong, Yueyang and Pingjiang areas of Hunan Province, and left some regular changes on the plane toward southeast: the overlying beds from absence to presence, the contact from high-angle to low-angle and then to parallel disconformities, and metamorphism of middle Proterozoic gradually getting weaker. From the tectonic point of view, the Wuling orogeny, with its central place as stated above, brought about the withdraw and final disappearance of the Southern China ocean basin, the formation of the South China Plate by collision and convergence between Yangtze Oldland and Cathaysia Oldland, and the ocean-continent conversion in the study region during the middle Proterozoic.
