四川省西南地区震旦系分布广泛,出露良好,顶底界线清楚。本区同时开展了生物地层、岩石地层及同位素地质年代学等方面的研究工作。为了给地层划分和对比提供古地磁方面的依据,进行了本专题的研究工作,经与湖北的古地磁资料对比,认为在震旦纪,苏雄与湖北似属于不同的地块,不过从震旦纪晚开建桥期到观音崖期,苏雄与湖北趋于联合,这两地区的地层可以粗略地对比,列古六组和南沱冰碛层都处于低纬度带,这与晚前寒武纪有全球冰川的观点一致。
The Sinian lines in southwestern Sichuan are widely distributed and well exposed with a clear top and bottom boundary. At the same time, this area has carried out research on bio-stratigraphy, lithostratigraphy and isotopic geochronology. In order to provide basis for the geomagnetism of stratigraphic division and contrast, the research of this topic was carried out. Compared with the paleomagnetic data in Hubei Province, it is considered that Sinian and Suxiong and Hubei belong to different plots, Danxian opened to the Guanyin Cliff late, Suxiong and Hubei tend to be united, the strata in these two areas can be roughly compared to the ancient Tuo Liu group and the Nantuo moraine layer are in low latitudes, Cambrian has the same view of the global glacier.
