摘　　要：广西下震旦统“南沱组”一名引自峡东地区震旦系剖面的南沱组。本文根据区调成果三江泗里口剖面资料,认为两地区述及的“南沱组”无论从岩性、岩相及沉积环境均有较大差异,桂北地区属冰川-海洋沉积,峡东地区属大陆冰川沉积,二者为同期异相产物。因此,建议更名为“泗里口组”较适宜。The name of Lower Sinian ' Nantuo Formation' in Guangxi is quoted from the ' Nantuo Formation' of Sinian section in eastern Sanxia area. Based on the result of regional geological reconnaissance-the information of Silikou section in Sanjian County of Guangxi, this paper believes that the' Nantuo Formations' in these two areas are obviouly different, not only in rock characteristics, but also in sedimentary facies and environment. Originaly, they were glacial-oceanic sediments in northern Guangxi area, continental glacial sediments in eastern Sanxia area; both were formed in the same period but of different facies. So it is suggested that substitution of Silikou Formation for Nantuo Formation is more reasonable in Guangxi.
