摘　　要：疆锋铁矿区内有原生磁铁矿和残坡积磁铁矿两个类型,以前者规模较大。原生磁铁矿矿体呈似层状、透镜状赋存于大勐龙群下段第三层(Ptdm^(1-3))变质岩系中,矿体产状与地层产状基本一致。为火山-沉积变质型矿床。地层层位及磁异常是主要的找矿标志。Jiangfeng Fe Deposit can be divided into original magnetite deposit and sedentary-slope wash deposit. And the former is larger than the latter. The ore body of original magnetite deposit is stratoid,lenticular,in Damenglong Group Lower Member 3^（rd）bed（ Pt_（dm）^（1-3）） metamorphic rock series. The occurrence of ore body is consistent basically with that of the strata. It is a volcanic sedimentary metamorphic type deposit. The principal prospecting criteria are strata horizon and magnetic anomaly.
