摘　　要：云南福贡县大和铁多金属矿区,磁铁矿体呈层状、透镜状赋存于古元古界崇山岩群b岩段(Pt_1~b)中,矿体明显受地层层位控制。含矿岩性为一套变质的角闪质岩,分别有角闪黑云变粒岩、角闪黑云片岩、黑云石英片岩等。该铁矿工业类型属需选铁矿的磁性铁矿,成因类型为火山-沉积变质型磁铁矿床。In Dahe Fe multimetallic orefield in Fugong,Yunnan,the magnetite orebody is bedded,lenticular in Palaeoproterozoic Chongshan Group Member b（Pt 1C^ b）,the orebody is controlled clear by the horizon of rock bed.The ore-bearing rocks are a suite of hornblende rocks including hornblende biotite granulite,hornblende biotite schist,biotite quratz schist,etc.The commercial type of this Fe deposit belongs to the magnetic Fe deposit which must be dressed for Fe ore,and it is a magnetite deposit of volcanic-sedimentation metamorphic type in genesis.
