【摘要】 通过对辽南苏皖地区晚前寒武纪地层的同位素年龄及生物化石的研究,及对辽南复州地区海岛子—袁家沟剖面的研究,认为该区原确定为晚前寒武纪地层的层序有叠接的错误。重新厘定的地层层序为永宁组(曹店组)、钓鱼台组(八公山组),南芬组(刘老碑组)、桥头组 (寿县组)、高家屯组(九里桥组)、洼里组和金山组(四顶山组)。震旦系与青白口系无空缺存在。更多还原

【Abstract】 The original sequence of Late Precambrian in south Liaoning is incorre- ct.The incorrectness lies in that the strata of different positions were taken as within the same position and those of the same position were considered in the form of superimposed strata of different positions.The similar mist- ake was also made about the sequence of Late Precambrian in the north parts of Jiangsu and Anhui provinces.The above opinions are reconformed by the fact that the original sequences are inconsistent with their biogenic fossils and isotopic ages available.So the author thinks it does not hold water that there is an absence between the Sinian and Qingbaikou systems.更多还原
