| 摘 要： | 晚二叠世合山组总体上是在低能的浅水局限台地中沉积下来的，由于海平面下降，局限台地露出水面，发生泥炭沼泽化，堆积泥炭．根据沉积学特征、生物组合类型及岩石组合类型，在合山组中识别出４种微相类型：单粒度基底型、双粒度单模式型、双粒度双模式型、过渡类型和７种沉积相：滨岸平原沼泽－泥炭沼泽相、潮上沼泽－泥炭沼泽相、潮上相、潮间－潮上沼泽－泥炭沼泽相、潮间相、浅水潮下相、较深水潮下相．

| Abstract: | he Upper Permian Heshan Formation of Heshan coalfield, Guangxi Province, is a shallow marine unit formed in a carbonate platform characterized by low-energy and semiclosed wave activity.The peat accumulated in swamps created on the carbonate platform by forced regressions during periods of relative sea-level fall. Based on the study of sedimentology, paleobiology and petrology,four microfacies-mono-grain basalia pattern,bigrain-monomodel pattern,bigraing-bimodel pattern and transition pattern-and 7 sedimentary factes-shoreplain bog-peat swamp factes I supratidal bog-peat swamp factes,supratidal factes,intertidal-supratidal bog-peat swamp factes, intertidal factes,shallow subtidal factes and deeper subtidal factes-have been recognized in the Heshan Formation. |
