摘要
通过在该地区进行1:5万区域地质调查工作及沉积相研究工作,系统地建立了该地区石炭纪地层的沉积序列。在沉积相研究基础上,肯定该区石炭系存在着三角洲沉积体系,并通过对比,说明为浅水三角洲沉积。
Through the work of 1/50000 regional geological survey and the research of the sedimentary facies in the area, the author systematically sets up sedimentary sequence of Carboniferous period stratum. On the basis of the study of sedimentary faies, he affirmed that there was a delta depositional system during the Carboniferous period in the area. It is a shallow delta deposition by analyzing comparatively.
