以重庆市城口县高燕锰矿为研究对象,对ZK127-7#钻孔进行岩心编录,揭露的地层由上到下依次为第四系堆积物、震旦系上统灯影组(5-1段),震旦系下统陡山沱组2段,锰矿主要赋存于陡山沱组顶部,严格受地层产出控制。对含锰岩系进行系统采样,测试了包括Mn、Fe、P、SiO2、CaO、MgO、Al2 O3、LOI共8个指标。结果表明,各组分含量差异较大,SiO2与Al2 O3、Fe的含量分布形态一致,CaO、MgO、LOI含量分布形态则与其相反；相关性分析结果印证了各主分含量的一致性和差异性；Mn/Fe、SiO2/Al2 O3、Al/( Al+Fe+Mn)值表明,含锰岩系中的Mn在富集成矿过程中存在与Fe分离的现象,锰矿层形成于相对潮湿的气候环境中,且形成过程中有热水注入。

Taking the Gaoyan manganese ore in Chengkou county,Chongqing city as the research object,the core logging for No. ZK127-7# drill core is carried out. The revealed strata from the drill core are quaternary sediments,Dengying formation of upper sinian system and Doushantuo formation of lower sinian system from top to bottom. Manganese ore mainly occurs at the top of the Doushantuo formation,and it is strictly controlled by the output of the strata. The manganese ore series are systemati-cally sampled so as to survey the concentrations of Mn,Fe,P,SiO2 ,CaO,MgO,Al2 O3 and LOI. The research shows that,there are great differences among the content of each component,the content distribution form of SiO2 is similar to that of Al2 O3 and Fe and opposite to that of MgO,CaO or LOI. The characteristics of consistency and difference of each component are confirmed by the correlation analysis results of different components. The elements ratio value of Mn/Fe,SiO2/Al2 O3 and Al/( Al+Fe+Mn) indicated that, the separation phenomenon of Mn and Fe in manganese rock series appears during the mineralization process. Manganese ore layer is formed in a humid environment with hydrothermal injection.
