Rotation and Uplift of the Taoxi Dome and Its Implication for the Evolution of Wuyi Terranes in Cathaysia Block

The Taoxi dome stands out as a rotated-circular structure on maps of the Wuyi terrane, south China. origin and tectonic activity analysis is window to understand framework aggregation process terranes in Cathaysia block. Our field observations demonstrated that two major phases deformation, counterclockwise rotation uplift, were recorded dome. Geochronological data indicated was initiated at about 422 Ma result sinistral slide collision between North terrane South along Nanping–Ninghua belt during Caledonian.
