MICROLITHOFACIES AND THEIR PEAT-FORMING MICROENVIRONMENTS OF EARLY PERMIAN (XIASHIHEZI FORMATION) SEAM B9b FROM XINZHANGZI MINE FIELD, HUAINAN COOL DISTRICT, P. R. CHINA

    摘要
  • 摘要: B9b煤层总体上形成于下三角洲平原环境，分为A、B、C、D、E五种岩石微相类型，分别对应于潮湿森林沼泽Ⅰ、Ⅱ、Ⅲ、Ⅳ及干燥木森林沼泽五类成炭微环境。成炭微环境以潮湿森林沼泽为主，在时间上经历了从干燥到潮湿的三个旋回演化历程。

     

    Abstract: The seam B9b, which was formed on a lower delta plain,was distinguished into five microlithofacies by light of coal petrology,and the microlithofacies derived respectively from five type of peat-forming microenvironments, i. e.,wet forest swamp Ⅰ、Ⅱ、Ⅲ、Ⅲ、Ⅳ and dry forest swamp. The microenviroments,in which the wet forest swamps were dominant,gone through three developed cycles (stages)from dry to wet in the peat-forming course of the seam.
