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(1.8~1.6 Ga)包括常州沟组、串岭沟组、团山子组、大红峪组,蓟县系(1.6~1.4 Ga)包括高于庄组、杨庄组、雾迷山组、洪水庄组、铁岭组,下马岭组归入蓟县系之上的待建系(1.4~1.2 Ga),不再属于青白口系,1.2~1.0 Ga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干群对应蓟县系。
Based on the new program of the National Mesozoic and Neoproterozoic Chronostratigraphy of China and recent research achievements in recent years, the lithology, isotopic ages, stratigraphic contact and strata relations of Mesoproterozoic strata in northeast China were studied. Inner Mongolia and Middle Proterozoic lithostratigraphic units were verified. The Great Wall series (1.8 ~ 1.6 Ga) in Liaoning Province, including Changzhou Gouzhan, Tanlonggou, Tuanshanzi, Dahongyu and Jixian (1.6 ~ 1.4 Ga) The Yuzhuang Formation, Yangzhuang Formation, Wumishan Formation, Hongshuang Formation, Tieling Formation and Xiamaling Formation belong to the line to be built (1.4-1.2 Ga) above the Jixian Series and no longer belonged to the Qingbaikou Estuary and 1.2-1.0 The strata of Ga are missing. The Heilongjiang group in Heilongjiang Province belongs to the Neoproterozoic, the Xiluohe Group in Jilin is disintegrated, the Laoling Group corresponds to the Lower Paleogene, and the Neogene in Inner Mongolia is similar to the Jixian Series.
