| 中文摘要: |
| 贵州梵净山地区南华系-志留系广泛沉积海相地层，由冰碛岩、陆源碎屑岩和碳酸盐岩组成（按时代排序）。本文以沉积学理论为基础，结合沉积相和沉积体系分析方法对研究区野外收集的地质资料，包括岩性组合、基本层序、沉积构造等进行分析，最终将区内南华系至志留系沉积体系划分为1个沉积体系组、3个沉积体系、10个沉积相和5个沉积亚相。南华纪-志留纪时期，按照沉积体系的不同，研究区经历了海洋陆源碎屑沉积体系（夹海洋冰川沉积）-碳酸盐沉积体系-海洋陆源碎屑沉积体系的变化。本文为区内层序地层研究和沉积盆地的充填及演化分析提供基础资料。 |

| In Fanjingshan area of Guizhou，sea facies strata deposited widely in Nanhua System-Silurian System，this strata was made of tillite，terrigenous clastic rock and carbonate rock（according to the epoch）On the basis of sedimentation，the geological information of the target area（lithology association，casic sequence，sedimentary structure and so on）were studied by the methods of sedimentary facies and sedimentary system，so the Nanhua System-Silurian System in this area was divided into 1 sedimentary system group，3 sedimentary systems，10 sedimentary facies and 5 sedimentary subfaciesIn Nanhua System-Silurian System，according to the difference of sedimentary system，the target area experienced the change of sea terrigenous clastic sedimentary system-carbonate sedimentary system-sea terrigenous clastic sedimentary system. In this paper，it will afford basic information for the study of sequence stratigraphy and analyses of sedimentary basin filling and evolution |
