【摘要】 <正>鄂湘粤桂晚二叠世煤系(龙潭组)相当发育,分布面积广泛,煤的岩石组成及变质特点复杂。多年来虽然对煤系分布、形成条件和成煤规律等问题,不少同志作过一些探讨,但很少深入系统地开展区域性的煤岩煤质研究工作,从区域特征和总的变化趋势上阐述其规律性。本文是在以往南方煤田煤岩工作实践的基础上,收集一定资料,并加以整理,提出
【Abstract】 In this paper,we chieflr described the petrographic composition of coal, its metamorphism,regional characteristics and change tendency,as well as the factor of influence on coal petrographic features and the types of its metamorphism.
