摘　　要：本文通过分析贵州镇宁县大营研究区晚二叠世龙潭组煤系地层特征,煤岩层对比分析,结合化石等,分析了龙潭组沉积环境,识别出障壁岛砂坝—潟湖相及三角洲相两种沉积类型,沉积环境对煤层的展布及煤质特征具有较为显著的控制作用,对周边煤炭资源的勘查和开采可起到一定的借鉴作用。This paper analyzes the sedimentary environment of the Late Permian Longtan Formation in Daying Research Area,Zhenning County,Guizhou Province by analyzing the stratigraphic characteristics of coal measures,coal-rock correlation analysis,combined with fossils,and identifies two sedimentary types:barrier island sand-lagoon facies and delta facies.The sedimentary environment has a significant control effect on coal seam distribution and coal quality characteristics.It can be used for reference in the exploration and exploitation of coal resources around.
