  The result of thermal imitation demonstrate that both the coal and dark argillite have stronger ability to the gasous hydrocarbon and the coal have specific ability to liquid hydrocarbon in upper Paleozoic. lithic sandstone and quartz sandstone is main rock type, composition maturity and structural maturity are mid-poor, The grain size parameter is 0.25-0.5mm In Shanxi Formation and Xiashihezi Formation In Yimeng exploration area, the content of matrix is high and change is stability, the content of cement are mainly clay mineral: illite, kaolinite, chlorite films, and carbonate minerals: ferrocalcite, calcite, dolomite, siderite and silica etc.

  粒度以中-粗粒为主。 填隙物组分含量高，但变化稳定，主要为粘土矿物伊利石、高岭石、绿泥石以及碳酸盐类矿物如铁方解石、方解石、白云石、菱铁矿以及部分硅质胶结。
