摘要
简单介绍了湖南元古宙论水铺群林家湾组正层型剖面和板溪群横路冲组正副层型剖面；对比了二组剖面的地层岩性和成岩时代及层位等特征；论证了沧水铺群林家湾组层位是合乎客观地质实际的；阐述了对湖南益阳沧水铺地区磨拉石一火山建造的划分对比讨论的重要意义。
This paper simply introduces both right Proterozoic geological sections of the LinjiawaFormation, Cangshuipu Group and Hengluchong Formation, Banxi Group in Hunan, China, respectively; in detail compares their main characteristics such as bed lithology, diagenetic epoch and Position in the Proterozoic; and demonstrates the Linjiawan Formation, Cangshuipu Group is congrUent with Hunan's Proterozoic rock strata sequence; as well as notes it is significant to study and to discuss the division and correlation of the molasse-volcanic formation at Cangshuipu, Yiyang County, Hunan.
