为了恢复郑州超化煤矿山西组沉积时盆地的介质环境条件，利用Ｘ射线衍射和等离子光谱分析技术对研究区泥质岩的粘土矿物和微量元素进行了分析，研究表明研究区泥质岩中微量元素和粘土矿物组成在二１ 煤层的上下明显存在差异：Ｂ、Ｓｒ／Ｂａ、Ｐ、ＣａＯ、ＭｇＯ、Ｖ、Ｌｉ、Ｎｉ、Ｚｎ 含量在底板泥质岩中含量较高，而在顶板以上泥质岩中含量明显降低；ＴｉＯ２、Ｃｕ 和Ｃｏ 含量在垂向上的变化趋势与上述元素相反；伊／蒙间层矿物和伊利石在底板泥质岩中含量较高，而顶板以上泥质岩中高岭石具有增高趋势。这反映出二１ 煤层底板明显受到海水影响，而在煤层形成以后海水影响明显减弱。
In order to restore the media environmental conditions of the basin during the sedimentation of the West Group of Chaohua Coal Mine in Zhengzhou, the clay minerals and trace elements of argillaceous rocks in the study area were analyzed by X-ray diffraction and plasma spectral analysis. The results show that trace elements Elemental and clay mineral compositions obviously differed from top to bottom in No. 2 coal seam. The contents of Sr, Ba, P, CaO, MgO, V, Li, Ni and Zn were higher in the bottom mudstone, The content of TiO2, Cu and Co in the vertical direction is opposite to that of the above elements. The contents of the Iraqi / interfacial minerals and illite are higher in the basement mudstone, Ridge has an increasing trend. This shows that the coal seam floor is obviously affected by seawater, and the influence of seawater is obviously weakened after the coal seam is formed.
