菏泽凸起西部含煤地层划分探讨

Study on Coal-bearing Strata Division in West of Heze Salient

摘要:

根据 1∶2 0 0 0 0 0区域重力和钻孔资料分析 ,1 980年编制的《山东省前晚第三纪基岩地质图 (1∶50 0 0 0 0 )》于菏泽凸起西部标示的石炭—二叠纪含煤地层区应是奥陶纪地层分布区。据此 ,对该地区的含煤地层进行了重新划分。

Abstract:

According to the data analysis, which are from regional gravity (1∶200,000) and drilling, the coal-bearing, carboniferous-Permian systems in west of Heze salient showed by “Geological Map of Early Neo-tertiary Base Rocks in Shandong Province ”(1∶500,000) published in 1980 should be coal-bearing Ordovician distribution area. On these grounds, coal-bearing strata in west of Heze have been re-divided in this paper.
