摘要
对长梁山地区磁铁矿形成的地质背景、矿体地质特征、成矿机制等进行了分析研究。结果表明,该磁铁矿矿石类型简单,主要为磁铁矿矿石,矿石品位较富。矿体产出严格受燕山期中酸性侵入岩及二叠系曲地组碳酸盐岩层位的控制,认为其成因为接触交代(矽卡岩)成矿。
In this paper, it analyses the geologic background, ore body geologic characteristic and metallogenic mechanism of the magnetite formation in Changliangshan area. It＇s found that the ore type of the magnetite is simple from the result, mainly is magnetite ore and the grade is high. The ore body occurrence is controlled strictly by neutral acid infracrustal rock in Yanshan stage and carbonate rock in Qudi formation of Dias, it＇s thought that the genesis is contact metasomatic （seam） mineralization.
