淮北矿区马家沟组碳酸盐矿床特征研究

Research on the Characteristics of Carbonate Deposits of Majiagou Formation in Huaibei Area

在对淮北地区马家沟组碳酸盐矿床区域分布调查的基础上,分析测试了矿区不同矿层的主要化学成分,对比了不同矿点各矿层的厚度变化和矿床的岩石化学组成,指出了3个矿层的厚度从北西向南东方向逐渐变薄的基本特征,以及3个矿层的主要化学成分CAO含量在剖面上,自下而上由高变低和MGO、SIO2含量由低变高的互为消长的规律。研究探讨了淮北地区马家沟组碳酸盐矿床的成矿背景。

Based on the investigation into the areal geological distribution of Majiagou formation carbonate deposits in Huaibei Area, the main chemical components of different ore beds in mining area are tested. And the thickness distributing rules and petrological characteristics of different mineral ledges are amply characterized. It points out basic characteristics of the thicknesses of 3 mineral layers that become thin gradually from the north west to south east, and the content of main chemical component CaO changes from high to low on the section＇s bottom to top, on the contrary the contents of MgO and SiO2 change from low to high. The Sedimentary environments and mineralizing conditions of mining area are concluded.
