摘要
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.
