| 中文摘要: |
| 为了寻找连续完整且有研究价值的南华系剖面、推进南华系建系工作。本文依据对湘黔桂交界地区南华系主要剖面观察研究所获资料，以沉积岩相类型分析、分布特点为线索，划分出了12种沉积岩相类型，在此基础上反演南华纪各主要阶段古地理环境。得出:南华纪湘黔桂交界地区北西侧为古陆、南东侧为南华裂谷盆地，南华纪早晚两个冰期仅在古陆与盆地过渡的浅海地带，也就是现今的湘黔桂交界地区存在连续完整的沉积，连续完整的具研究价值的南华系剖面应在该区域寻找这一结论。 |

| The purpose of this article is to find a continuous，complete，and research-worthy Nanhuan section and to promote the establishment of its SystemIn this paper，based on the data obtained from the observation and research of the main sections of the Nanhuan in Hu’nan- Guizhou-Guangxi border area，the types of sedimentary facies and their distribution characteristics，12 types of sedimentary facies are classifiedThe paleogeographic environment of the main stages of the Nanhuan Period has been inverted from thisIt is concluded that the northwestern part of the south China Yangtze area is paleocontinent and the southeast is the rift basin during the Nanhuan PeriodThe two glacial periods(beginning and ending)continuous and complete sedimentation existed only in the transitional shallow sea areas between paleocontinent and basin，that is，the current junction of Hunan Guizhou and GuangxiThe continuous and complete Nanhuan System section with research value can only be found in this area |
