根据古地磁、古气候、古生物群分布特征及地史时期区域沉积建造分布特征等研究资料,中国大陆自古生代以来七拼八凑形成的.太古代晚期(十八亿年前),中国境内仅有两块不大的,近东西向亚铃状分布的中朝古陆和塔里木古陆.就中朝古陆分析,太古界与震旦亚界的沉积建造之间有明显的角度不整合,两者同位素年龄值也相差很大,说明本区太古代末曾一度隆起成陆.
According to ancient geomagnetism, palaeoclimate, distribution of paleontology and the distribution characteristics of sedimentary structures in geo-history, the mainland of China has been formed in a patchwork since the Paleozoic. In the late Archean (1.8 billion years ago), only There are two small, nearly east-west Asian bell-shaped ancient landlocked and Tarim ancient land.As for the analysis of the Sino-North Korea ancient land, there is a clear angle of unconformity between the deposition of the Arctic and the Sinian subcontinent, Both isotopic age values also vary greatly, indicating that the region was once uplift into the Archean.
