1922年葛利普根据我国早期地质工作者的资料和要求,把“震旦系”作为一个时间地层单位古生界的第一个系提出来,而其含义过于笼统而广泛,可以装进大量的、时间范围很长的地层。1924年李四光在长江峡东区确定了一个厚不过800米,时间范围较小的“震旦系”。1934年高振西等在河北蓟县又确定了一个厚达10000米,时间长达10多亿年的大“震旦系”。自此我国就存在以峡东剖面为标准的南方型和以蓟县剖面为标准的
In 1922, based on the data and requirements of early geologists in our country, Gelip put forward the “Sinian system” as the first department of Paleozoic in a temporal stratigraphic unit. Its meaning is too general and extensive, A very long time horizon. In 1924 Li Siguang in the Yangtze River Gorge East identified a thick 800 meters, the time range smaller “Sinian.” In 1934, Gao Zhenxi et al identified a large “Sinian” in Jixian County, Hebei Province, with a thickness of 10,000 meters and a duration of more than 1 billion years. Since then, there exists a southern type with the Gorge East profile as a standard and a section with the Jixian profile
