摘　　要：华北地台东缘—东南缘的胶辽徐淮地(层)区发育了一套中—新元古代海相碎屑岩与碳酸盐岩地层,通常不整合覆于太古宇或古—中元古界之上,平行不整合伏于寒武系之下,在安徽和江苏北部、山东中—西部和山东半岛、辽东半岛以及吉林南部等地区出露良好。前人对于胶辽徐淮地区中—新元古界的划分和对比,尤其是该套地层的时代归属,长期存在不同的认识。在2014年出版的《中国地层表》中,辽南地区的细河群桥头组被归入南华系,而五行山群和金县群被划入震旦系(埃迪卡拉系)。近年来越来越多的岩石地层学、生物地层学、同位素化学地层学,尤其是同位素年代地层学的证据表明,淮南地区的淮南群—肥水群、淮北地区的淮北群、鲁西地区的土门群、胶东地区的蓬莱群、辽南地区的永宁组—细河群—五行山群—金县群、吉南地区的白房子组—细河群—浑江群都是中元古代晚期—新元古代早期(拉伸纪)的沉积地层。Meso-Neoproterozoic successions in the eastern and southeastern margins of the North China Craton, also known as the Jiao-Liao-Xu-Huai stratigraphic realm, consist of thick marine siliciclastic and carbonate rocks. Generally, they sit unconformably on Archean or Paleo-Mesoproterozoic metamorphic rocks, and unconformably underlie the Cambrian rocks. In the Jiao-Liao-Xu-Huai area, the Meso-Neoproterozoic strata crop out mainly in northern Anhui and Jiangsu provinces(“Xu-Huai”, including the Huainan, Huaibei, and Xuzhou areas), western and central Shandong Province and Shandong Peninsula(“Jiao”, including the Luxi and Jiaodong areas), Liaodong Peninsula(“Liao”, the Liaonan area), and southern Jilin Province(the Jinan area).Different stratigraphic schemes have been proposed for the subdivision and correlation of Meso-Neoproterozoic successions in the Jiao-Liao-Xu-Huai area. In the Stratigraphic Chart of China(2014), the Qiaotou Formation of Xihe Group has been assigned to the Nanhuan System(roughly equals to the Cryogenian System), and the Wuhangshan and Jinxian groups have been assigned to the Sinian System(equals to the Ediacaran System) in the Liaonan area. In recent years, more and more lithostratigraphic, biostratigraphic, chemostratigraphic, and especially radiometric geochronological data show that the Huainan and Feishui groups in the Huainan area, the Huaibei Group in the Huaibei area, the Tumen Group in the Luxi area, the Penglai Group in the Jiaodong area,the Yongning Formation and the Xihe, Wuhangshan, and Jinxian groups in the Liaonan area, as well as the Baifangzi Formation and the Xihe and Hunjiang groups in the Jinan area are of late Mesoproterozoic to early Neoproterozoic(Tonian) in age.
