| 摘 要： | 随着国民经济的快速发展,传统的铁矿资源越来越紧缺,迫切需要寻找和开发非传统的铁矿资源。河南嵩县南岭超贫磁铁矿(mFe,其含量为10.20%)品位低,易采易选,性质上可归属于非传统矿产资源。通过对南岭超贫磁铁矿的磁铁矿石、斜长角闪(片)岩化学成分的对比分析,结合矿区地质特征和矿体特征,对矿体进行n(Fe+Al+Ti)-n(Ca+Mg)和w(FeO+Fe2O3+TiO2)-w(Al2O3)-w(MgO)图解分析,结果显示南岭矿区的含磁铁斜长角闪(片)岩和斜长角闪(片)岩是大洋富铁拉斑玄武岩经变质作用而形成的,矿床的成因类型为风化残积型超贫铁矿床。进一步厘定了找矿标志,建立了找矿模式,对寻找南岭型铁矿有一定的借鉴意义。

| Abstract: | Along with the fast development of national economy,the traditional iron resources are more and more scarce,it is urgent to seek and to develop non-traditional iron resources.The Nanling ultra poor magnetite can be imputed non-traditional mineral resource with mFe content of 10.20%.Through the contrast analysis on the chemical constitution of the magnetic iron ore and the plagioclase-amphibolite in Nanling ultra poor magnetite,and the analysis of graphs of(Fe+Al+Ti)-(Ca+Mg) and(FeO+Fe2O3+TiO2)-Al2O3-MgO,com... |
