摘 要:根据全国地层委员会中国中新元古代地层年表的新方案和近年的来新研究成果,对东北地区中元古代地层岩性、同位素年龄、叠层石以及地层接触关系等进行了研究,对区内中元古界岩石地层单位进行了核实,辽宁的长城系(1.8~1.6Ga)包括常州沟组、串岭沟组、团山子组、大红峪组,蓟县系(1.6~1.4Ga)包括高于庄组、杨庄组、雾迷山组、洪水庄组、铁岭组,下马岭组归人蓟县系之上的待建系(1.4~1.2Ga),不再属于青白口系,1.2~1.0Ga的地层缺失;黑龙江省的黑龙江群归入新元古界,吉林的色洛河群解体,老岭群对应长城系下统;内蒙古东部白云鄂博群和什那于群对应蓟县系。On the basis of the new Chinese Geologic Time Scale of the Meso- and Neoproterozoic strata and new achievements in recent years, the Mesoproterozoic strata lithology,isotopic age, stromatolite and contacting relationship of Northeast China Were studied. Lithostratigraphic units were verified. The Changcheng System (1.8- 1.6 Ga) of Liaoning Province included Changzhougou Formation, Chuanlinggou Formation,Tuanshanzi Formation, Dahongyu Formation. The Jixian System (1. 6Ga- 1. 4 Ga) included Gaoyuzhuang Formation, Yangzhuang Formation,Wumishan Formation, Hongshuizhuang Formation, Tieling Formation. Xiamaling Formation belonged to the Unnamed System (1.4- 1.2 Ga) up the Jixian System and no longer belong to Qingbaikou System. The strata of 1.2 - 1.0 Ga were absent. Heilongjiang Group in Heilongjiang Province was belonged to Neoproterozoic. Seluohe Group in Jilin Province was disassembly,and no longer belong to Mesoproterozoic. The Laoling Group corresponded to the Lower Series of Changcheng System. Baiyunebo Group and Shinagan Group in eastern Inner Mongolia corresponded to the Jixian System.
