摘要
选择了贵州贵定闻江寺、广西合山马滩和来宾蓬莱滩剖面，从生物地层学的角度综合论证了黔桂地区上二叠统中的煤层对比问题，认为吴家坪阶下部的煤层是东吴运动之后海侵初期的产物，贵定地区长兴组上部的煤层与合山地区的Ⅰ、Ⅱ煤大致相当，而其它煤层则是由于局部地域的沉积基底相对抬升所形成的。
ased on the data from the Wenjiangsi Section in Guiding,Guizhou,the Matan Section in Heshan and the Penglaitan Section in Laibin,Guangxi,the present paper mainly deals with the correlation of the Late Permian coal seams in these localities from the biostratigraphic viewpoint.It is found that the coal seams in the lower Wujiapingian in these localities were formed by the earliest transgression in the Late Permian after the Dongwu Movement and the coal seams in the upper part of the Changxing Formation in Guiding approximately correspond to the Coal Seam-- ⅠorⅡin the Heshan Section,whereas the other coal seams in these localities are only resulted from the relatively partial rise of the sedimentary bases.
