摘    要:通过地层对比、岩相及生物组合分析,表明乌当地区的旧司组从田坝头到苗天之间沉积环境由潮坪-滨湖相变为砂坪-泥坪相,沉积物由灰岩夹炭质页岩渐变为石英砂岩夹灰绿色页岩。合理地解释了它们之间的关系及空间的展布规律。

关 键 词:旧司组 祥摆组 贵阳市 沉积环境 石炭系

Abstract:Through the analyses of the stratigraphic correlation,the lithofacies and the biocanoes,it is concluded that the depositional environmert of the Jiusi Formation changed laterally from the coastal facies to the sand and mud flat facies,while the rocks changed from the limestone interbedded carbonaceous shale(the Jioushi Fm.)to the quartz sandstone interbedded the grey green shale (Xiangbai Fm.), This gives a proper explanation to the relation and the distribution of the Jioushi and the Xiangbai Formations.
Keywords:Wudang of Guiyang  the Jiushi Formation  the Xiangbai Formation  the Facies Change.
