| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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 coalseam distribution and coal quality characteristics. It can be used for reference in the exploration and exploitation ofcoal resources around. |
