摘　　要：湘黔桂相邻区发育一套序列完整、界面清楚的武陵造山运动不整合面之上至震旦纪（820-635Ma）时期的裂谷盆地沉积地层.通过详细的区域岩石地层划分与对比,结合年代学研究成果,显示其时空展布格局完整,充填序列连续,划分标志清楚,完全可以划分对比.在此基础上建立了其地层格架,为扬子古大陆周缘新元古代820-635Ma时期地层划分对比研究提供了详实的资料,亦为中国前寒武系新元古代地层划分对比及国际新元古代研究提供了新的资料成果。A set of Neoproterozoic(820- 635 Ma)sedimentary strata are developed in Hunan, Guizhou and Guangxi, which occur above the Wuling Movement and below the Zhendan System, serving as the formation of lift basin with the well developed succession and clear sedimentary boundary. The stratigraphic system, according to the stratigraphical division and correlation of the regional rock and strata in combination with the recent results of chronology, shows a completed distribution and evolution,successive strata, and a clear division mark; it therefore can be completely divided and contrasted. On the basis of the stratigraphic division and correlation, the authors formulated a stratigraphic framework, which presents a set of detailed and accurate data for studying the stratigraphic division and correlation of the Neoproterozoic( 820- 635 Ma) sedimentary strata in the YangtzePaleocontinent, and also offers the new resultant data for studying the Precambrian including the Neoproterozoic in China.
