摘　　要：新平东么铁铜矿区变质辉长辉绿岩、钠变质辉长辉绿岩发育,具有厚度较大、近地表次火山岩和铁、铜矿成矿专属性等特征,钠长石化、绿泥石化、黑云母化等围岩蚀变强烈,铁铜矿(化)体主要呈似层状、透镜状产出,受次火山岩体及次火山机构控制明显,矿床成因类型为受变质次火山气液钠化交代型。成矿地质条件优越,具有进一步的找矿前景。In Dongme Fe-Cu orefield of Xinping,the metamorphic gabbro-diabase,sodium metamorphic gabbro-diabase are developed,with very thick,near surface subvolcanic rock and Fe,Cu metallogenesis specialization,etc characteristics,albitization,chloritization,biotization,etc wall rock alteration intense,Fe-Cu orebody(metallogenesis)mainly stratoid,lenticular,controlled by subvolcanic rockbody,subvolcanic mechanism clear.It is the metamorphosed subvolcanic gas-liquid sodium metasomatic deposit in genesis,metallogenesis condition excellent,with further prospecting potentiality.
