本文论述了滇东滇池断裂带以东以及滇东北地区连续完整的前寒武系与寒武系界线地层剖面自下而上的层序是旧城段、白岩哨段、“小歪头山段”、待补段、中谊村段、大海段、石岩头段、玉案山段。论证了晋宁王家湾剖面待补段位于“小歪头山段”之上;晋宁梅树村剖面“小歪头山段”磷质条带中的小壳化石是中谊村段向下渗漏的产物,它在岩性上与白岩哨段无多大区别,可归入同一地层段范畴,恢复原命名的白岩哨段涵义。论述了以云南晋宁梅树村剖面为代表的滇池断裂带以西地区前寒武系与寒武系界线地层剖面有沉积间断,缺失了待补段沉积和大海段上部的瘤状白云岩,从而增补了梅树村阶大海段的一个化石带Heraultipegmayunnanensis,基本上肯定了梅树村阶有四个化石组合带。最新研究表明,滇东前寒武系与寒武系最佳界线地层剖面应是滇东北会泽雨碌和大海剖面。滇东前寒武系与寒武系的界线应放在中谊村段与待补段之间,即最古老的小壳化石组合之底。
This paper discusses that the continuous sequence of the Precambrian and Cambrian stratigraphic sections east of the Dianchi fault zone in east Yunnan and northeast Yunnan is from the Lower Reaches of the Old City and the White Rock and the “ ”To be supplemented paragraph, in the Yi Village section, the sea section, the first section of rock, jade mountain section. It is demonstrated that the section to be complemented in Wangjiawan section of Jinning is located above the “small tilt head section”; the small shell fossils in the “small tilt head section” Leakage product, which is not much difference in lithology and white rock whistle, can be grouped into the same strata category, restore the original meaning of Bai Yan whistle. This paper discusses the sedimentary discontinuities of Precambrian and Cambrian stratigraphic sections in the west of Dianchi Lake fault zone represented by the Meishu Cun section of Jinning, Yunnan, and lacks the sedimentary dolomite to be complemented and the upper part of the large sea section so that Heraultipegmayunnanensis, a fossil belt of the sea section of Meishu village, was added to confirm that there are four fossil assemblages in the village of Meishu. The latest research shows that the best boundary stratigraphic profile of the Precambrian and Cambrian in eastern Yunnan should be the Huize and the sea profile in northeastern Yunnan. The boundary between Precambrian and Cambrian in Eastern Yunnan should be between the Zhongyi Village and the area to be complemented, that is, the bottom of the oldest small fossil assemblage.
