摘要
贵州省晚二叠世海相矿区主要煤系地层是二叠系乐平统吴家坪组(P_(3)w),主要分布于贵阳—荔波小区及务川—天柱小区内,桐梓、贵阳、兴仁一线以东地区,区域上自西向东龙潭组逐渐过渡到吴家坪组。本次工作选择位于贵州省中部典型的海相吴家坪组含煤地层进行实测剖面并采集顶底板样和煤样,较明显地反映了含煤地层沉积环境特征,为一套海相的含煤沉积建造。
The main coal-bearing strata in the Late Permian marine deposits in Guizhou Province are the Wujiaping Formation(P_(3) w),which is mainly distributed in the Guiyang-Libo community and the Wuchuan-Tianzhu district,east of the Tonglu,Guiyang and Xingren lines.From the west to the east,Longtan group gradually transitioned to the Wujiaping Formation.In this work,the typical marine coal-bearing strata of Wujiaping Formation located in the central part of Guizhou Province were selected to measure survey section,collect samples of roof and floor,and collect coal samples,which clearly reflected the sedimentary environment features of coal-bearing strata and was a set of marine coal-bearing sedimentary formations.
