摘要
贵州茅坝天生桥位于黔北川黔交界地,其晚二叠世龙潭组为一套砂泥互层及煤层等沉积组合,具水平层理、透镜状层理及小型交错层理等沉积构造.。研究其岩石特征、沉积构造、层序等特征,查明该区上二叠统含煤沉积环境为潮坪-泻湖沉积体系及成煤环境。
Tianshengqiao is located in north Guizhou,the Sichuan-Guizhou border region.The Upper Permian Longtan Formation here is composed of grayish claystone,grey and black argillite,sandstone and coal seam with horizontal bedding,lenticular bedding and cross bedding.The study of lithologic character,sedimentary structure and stratigraphic sequence indicates that the Longtan Formation belongs to tidal flat-lagoon sedimentary system and coal-forming environment.
