本文系统总结了四十多年来对云南寒武系调查研究的成就,特别是近二十年来的新进展。首次将云南的寒武系作了地层分区,划分为2个一级地层区,6个分区及8个小区。将云南的寒武系作了划分,建立了标准地层系统和化石带。下统以滇东分区的梅树村组,筇竹寺组,沧浪铺组及龙王庙组为标准;中上统以滇东南分区的大丫口组、田蓬组、龙哈组、歇场组、唐家坝组及博菜田组为标准,共分为10个组25个化石带。各分区亦作了分组和化石分带。本文讨论了云南寒武系的上、下界线及分统界线,寒武纪时期的岩相古地理概况及生物群特征,共划分为10个时期进行了论述。其次,云南的寒武系与国内四川、贵州、湖北及华北等省区的作了比较,同时与邻国越南、缅甸、巴基斯坦的亦作了对比。阐述了云南不仅在国内是研究寒武系的一个重要地区,而且在国际上研究寒武系也占有相当的地位。
This article systematically summarizes the achievements made in the investigation and study of the Cambrian in Yunnan in the past forty years, especially the new progress in the past 20 years. For the first time, the Cambrian of Yunnan Province has been stratigraphically subdivided into two first-level strata zones, six sub-zones and eight sub-zones. The Cambrian of Yunnan Province was divided into a standard stratigraphic system and fossil zones. The lower member of the Middle East Division of the Meishucun group, Qiongzhusi group, Canglangpu group and the Longwangmiao group as the standard; Middle Yunnan to Southeast Yunnan Yakou group, Tian Peng group, Long Ha group, Field group, Tangjiaba group and Bo Caitian group as a standard, is divided into 10 groups of 25 fossils. Subdivisions have also been divided into groups and fossil zones. This paper discusses the upper and lower boundaries of the Cambrian in Yunnan Province, the boundary of the sub-system, the lithofacies palaeogeography and the characteristics of biota in the Cambrian era, which are divided into 10 periods. Second, the Cambrian in Yunnan Province has been compared with other provinces in Sichuan, Guizhou, Hubei and North China, as well as Vietnam, Myanmar and Pakistan. It expounds that Yunnan is an important area not only in China but also in studying Cambrian in the world.
