| Abstract: | In this paper,tne autnors report me study of me Sman-Camorian Doundary in E-NE Yunnan and W-SW Sichuan region.In this region the stratigraphic sequence of Sinian and Cambrian is perfect with unilithofacies,larger thickness,abundant fossils.It is an important region for studying and dividing the Sinian-Cambrian boundary in China.The Meishucun Stage is widely developed in the region studied.The authors have described and correlated the lithofacies,thickness and fossil assemblage of the Xiao-waitoushan member,Zhongicun member and Badaowan member distributed within this region.It is considered that the Badaowan member should be ascribed to the Meishur cun Stage. |
