The northern Yangtze Block went through many periods of deformation, within which the early-period structural styles were destroyed and replaced by later ones. Fortunately, records of the early-period deformation styles are reserved in the Nanzhang area, which is tectonically located between the two arc-shaped fault-belts in the northern Yangtze Block: Daba Shan and Dahong Shan. Three phases of folding were recognized in the Dayang synclinorium area, namely the first stage NW-SE trending folds, second stage NE-SW trending folds, and the third stage E-W trending folds. The three phases of folding correspond to the tectonic deformations such as the northward subduction of the Yangtze Block with later intra-continental deformation, the northwest-ward thrusts of the Jiangnan-Xuefeng fold blets and the southwest-ward propagation of Daba Shan fault belts during the late Jurassic to early Cretaceous, respectively.
