Abstract:Based on the research of geology and geophysics, two fault zones——NWW—EW and NE—NNE trending developed in the southern North China Craton (NCC). Among that, Jiaozuo—Shangqiu fault, Lushan—Fuyang—Huainan fault, Luanchuan—Gushi—Feizhong fault, Tancheng—Lujiang fault and Xiayi—Woyang—Macheng fault have characteristic of structural subarea. Besides, according to the analysis of aeromagnetic anomaly, the writers divide southern NCC and adjacent areas into Qinling—Dabie aeromagnetic anomaly zone and southern NCC aeromagnetic anomaly area. Furthermore, the latter can be divided into western Henan, eastern Henan, Xiayi—Woyang and Xuzhou—Huainan aeromagnetic anomaly area. Combined with research of fault systems in structural subarea, the writers 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 faultedbasin which the Xuzhou—Huainan basin area has the characteristic of NW trending thrust faults and associated with linear folds and faultedbasins.
