| 摘 要： | 潞西地区航磁有三个异常带：第一异常带为同源重磁异常，反映高密度磁源体，由基性～超基性岩引起；第二异常带区域不同源重磁异常，反映低密度磁源体为混合片麻岩、混合岩等低密度地层，局部可能反映团坡厂和轩岗乡与黄铁矿相类似的矿床（点）；第三异常带，重磁异常也不同源，反映寒武系一第四系的新地层，局部与花岗岩接触带及与断裂破碎有关的矽卡岩型铅锌多金属矿。依据区内航磁异常及地球物理特征，提出在潞西地区的找矿思路和方向。

| Abstract: | There are 3 zones of air magnetic anomaly in Luxi area ： zone 1 is the cognate gravity magnetic anomaly, which shows the high density magnetic source body of basic - ultrabasic rocks; zone 2 is the regional noncognate gravity magnetic anomaly, which shows the low density magnetic source body of low density rocks of migmatitic gneiss and migmatite and locally maybe the ore deposit similar to pyrite at Tuanpochang and netic anomaly, which shows Cambrian deposit related with granite contact and Xuangangxiang ; zone 3 is also the noncognate gravity mag- -Quatemary strata and locally skam Pb -Zn muhimetallic fault fracture. The prospecting idea and direction in Luxi area are put forward according to the air magnetic anomaly and characteristics of geophysics in this area. |
