On the basis of the latest exploration data ,the geochemical data and isotopic dating data, discussed geochem-ical characteristic and metallogenic model of ShongHu iron mine.The trace element of Songhu iron mine was depleted in Nb, Ta, P, Ti and it has the characteristics of geochemical of epicontinental volcanic island.Rare earth element analysis shows that the distribution pattern of orebody was similar with surrounding rocks,only had difference in total REE,it shows that the material source of orebody had correlation with surrounding rocks.It is considered that the metallogenic matarials originated from partial melting of oceanic crust and mantle.LA-ICP-MS zircon U-Pb age of roof is (332±1) Ma, the floor is (316.04±0.82) Ma.The conclusion indicated that Songhu iron mine belongs to magmatic-hydrothermal com-posite deposit which is related to volcanism.%据松湖铁矿勘探资料及地球化学数据、同位素测年数据，探讨松湖铁矿床地球化学特征及成矿模式。松湖铁矿微量元素表现出Nb，Ta，P，Ti亏损，具陆缘火山岛弧地球化学特点。矿体与围岩稀土元素分布模式相似，表明矿体与围岩物质来源具相关性。成矿物质来源于洋壳部分熔融及地幔，矿体顶、底板凝灰岩LA-ICP-MS锆石U-Pb年龄分别为（332±1）Ma和（316.04±0.82）Ma，认为松湖铁矿属与火山作用有关的岩浆-热液复合型矿床。
