对松湖铁矿和备战铁矿矿床地球化学进行对比研究表明,松湖铁矿产于陆源岛弧环境,先由火山作用形成沉积型铁矿,后形成含矿热液加富矿床;备战铁矿产于大洋岛弧环境,前期通过沉积作用成矿,后期在矽卡岩化作用下矿体富集成矿。
The comparative study on the geochemistry of Songhu Iron Mine and Bei’an Iron Ore Deposit shows that the Songhu Iron Mine is produced in the arc of terrigenous land source and formed the sedimentary iron ore by volcanism at first and then formed ore-bearing hydrothermal and enriched ore deposit. In the oceanic arc environment, the ore bodies were formed by sedimentation in the early stage and the ore body enriched and mineralized in the later stage under the skarnization.
