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。
蓮東鐵礦是沉積變質型鐵礦，成礦母巖為太古界老變質巖，區域變質作用為成礦提供動力。通過對磁法異常分析和驗證，髮現兩條有一定規模的礦體。礦體似層狀，礦石類型以磁鐵礦為主，近礦圍巖蝕變主要為硅化、碳痠鹽化、綠泥石化。根據礦體特徵和成礦規律分析，認為在太古界老變質巖中具有較好的找礦遠景。

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 quasibedded, ore types are mainly magnetite,alterations of near-ore wall rock are mainly silicification,carbonatization and chloritization.According to the characteristics of orebody and metallogenic regulation,it has a potential for prospecting in ancient Archaean metamorphic rocks.
