摘　　要：织金地区位于黔西晚二叠世陆源碎屑沉积的东北缘，为龙谭型含煤沉积，属障壁—泻湖体系。该区煤系上部２煤段的沉积特征代表了一种低能、小规模的障壁—泻湖体系，沉积相由潮坪、淡化泻湖、泥炭沼泽和低能障壁相组成，可称为低能障壁—泻湖含煤沉积体系。The Zhijing area is located in the northeast margin of the Late Permian terrigenous clastic deposits in western Guizhou province.The Late Permian coal bearing deposits in the area are the Longtan type of one and belong to the barrier lagoon system.The section with coal No.2 of the upper coal measures in the area discussed in the paper represents a kind of low energy and small scale barrier lagoon system,which is composed of tide flat,freshening lagoon,peat swamp and low energy barrier facies and is suggested to be called as coal bearing low energy barrier lagoon depositional system
