Combined with research of fault systems in structural subarea, the authors divided the southern NCC in Meso—Cenozoic into western Henan basin—ridge area, eastern Henan Basin area and Xuzhou—Huainan Basin area. The western Henan basin—ridge area has the characteristic of partitioning distribution among the Songxian—Tantou, Luoning—Lushi, Lingbao—Zhuyang Basin and Xiong’er Mountain, Yaoshan Mountain, Xiaoqinling Mountain. The eastern Henan Basin area develops NWW trending extensional faulted-basin which the Xuzhou—Huainan Basin area has the characteristic of NW-trending thrust faults and associated with linear folds and faulted-basins.
