摘　　要：曼养铁矿矿体呈似层状产出,主要赋存于古近系细碧岩、细碧角斑岩、钠长斑岩、火山角砾岩等火山碎屑岩中,矿体围岩蚀变主要有钠长石化、碳酸盐化、硅化、褐铁矿化、菱铁矿化等,其中以钠长石化与铁矿富集关系密切。成矿物质来自于岩浆,矿床受火山机构控制明显,属火山喷溢沉积、后期热液变质改造叠加铁矿床。The ore body ol Manyang Fe deposit is stratoid, mainly in Paleaogene spilite, spilite leratophyre, albitophyre and volcanic breccias. The main alteration ol wall rock are albitization, carbonatization, silicilication. Limonitization, sideritization, etc. And the albitization is in close relation to the Fe Metallogenesis. The metallo- genetic material is originated Irom the magma.. The ore deposit is controlled clear by the volcanic mechanism, be-longing to the Fe deposit ol volcanic eflusive depositation superimposed by metamorphic relormation..
