【摘要】 莲东铁矿是沉积变质型铁矿,成矿母岩为太古界老变质岩,区域变质作用为成矿提供动力。通过对磁法异常分析和验证,发现两条有一定规模的矿体。矿体似层状,矿石类型以磁铁矿为主,近矿围岩蚀变主要为硅化、碳酸盐化、绿泥石化。根据矿体特征和成矿规律分析,认为在太古界老变质岩中具有较好的找矿远景。更多还原

【Abstract】 Liandong iron mine is a sedimentary-metamorphic iron mine,the mother rocks are ancient Archaean metamorphic rocks,regional metamorphism provide the impetus for mineralization.Through the analysis and verification of magnetic anomalies,two belts of certain amount of ore were discovered.Ore laid quasi-bed- ded,ore types are mainly magnetite,alterations of near-ore wall rock are mainly silicification,carbonatiza- tion and chloritization.According to the characteristics of orebody and metallogenic regulation,it has a po- tential for prospecting in ancient Archaean metamorphic rocks.更多还原
