论杜瓦背斜侏罗系地层含煤性

Brief introduction to coal character of jurassic stratum in Duwa anticline

根据实地地质工作取得的地质资料,通过对杜瓦背斜各分区侏罗系地层的岩性分析,进行了地层对比,探讨了杜瓦背斜各分区侏罗系地层的沉积环境、含煤性及其影响因素。认为由于构造活动在三个分区的不均衡性,各分区的地壳出现不均衡沉降,以及断陷盆地基底起伏不平,形成不同的沉积环境,是造成了含煤性的差异的主要原因。指出杜瓦背斜南翼杜瓦河西岸地区是主要含煤区段,是今后煤炭资源进一步勘探开发的有利靶区。

According to the geologic data on the spot , through lithology analysis and stratum comparison, the artile discuses coal character and manipulative complication of Jurassic stratum in Dowa anticline. We think conformation disproportion moves about in three Subaru in divisional lithosphere appears unbalanced sedimentation and basin抯 floor is gurgitation disaffection ,therefore another aggravation circumstance is found to have appeared in divisional stratum. Then the author points out elementary opinion about the exploitation of Dowa Anticline
