摘　　要：研究区位于昆中花岗岩-变质杂岩隆起带东缘与鄂拉山岩浆带衔接部位,属昆中银、金、铜、铅、锌成矿带,带内发现了一系列银、金多金属矿床。通过物化探异常特征分析,研究区内圈定3处矿化蚀变带,12条多金属矿(化)体,矿(化)体严格受沿断裂构造形成的矿化蚀变带控制,主要以北西向和南北向断裂为主,蚀变矿化以强硅化、褐铁矿化、黄铁矿化、方铅矿化为特征,成矿地质条件良好,具有较好的找矿空间。The area is located at the junction between the eastern margin of Kunzhong granite-metamorphic complex uplift belt and the Erashan magmatic belt,which belongs to the Kunzhong Ag-Au-Cu-Pb-Zn metallogenic belt.A series of Ag-Au polymetallic deposits have been found in the belt.In analyzing geophysical-geochemical anomaly characteristics,we have made a research of the area selects in three mineralized alteration zone and 12 polymetallic mineralized bodies.It is strictly controlled by the fracture structure formation of the mineralized alteration zone,mainly from western north to southern north in fracture.Alteration and mineralization in strong silicification,limonite,pyrite,galena into characteristics are all good,including metallogenic geological condition.It has a good prospecting space,we think.
