摘要
对于姜驿铁矿矿床成因,前人均认为属中基性火山—沉积变质岩型贫磁铁矿。通过进一步工作,发现在矿化体中局部存在高品位致密块状磁铁矿脉,该高品位磁铁矿应为岩浆分异—贯入形成的矿体。
As to the genesis of Jiangyi Fe deposit, predecessors think that it belongs to intermidiate-basic vol- canic-sedimentary metamorphic rock type poor magnetite deposit. In the further work, it has been discovered that there is the local high grade dense magnetite vein in the metallogenetic body, which must be the orebody formed by magmatic differentiation-penetration.
