摘　　要：赵家沟钼矿为隐伏矿床,矿体产于燕山期早期中-晚侏罗世细粒花岗岩中,呈似层状、透镜状、脉状大致平行分布,钼矿石中的金属矿物以辉钼矿为主,黄铁矿、方铅矿、闪锌矿等次之,非金属矿物主要有石英、斜长石、钾长石等。围岩蚀变主要有硅化、钾化、绿泥石化等,与成矿有关的蚀变主要为硅化。钢屯镇赵家沟钼多金属矿属岩浆热液型钼矿床。The Zhaojiagou molybdenum deposit is a concealed deposit.The ore bodies are produced in the granite and are distributed in a roughly parallel manner in a sheet-like,lens-like and vein-like form.The main metallic minerals in the molybdenum ore are molybdenite,followed by pyrite,galena and sphalerite.The main non-metallic minerals are quartz,plagioclase and potassium feldspar.The wall rock alteration mainly includes silicification,potash alteration and chloritization,and the alteration related to mineralization is silicification.The Zhaojiagou molybdenum polymetallic deposit in Guantun Town is a magmatic hydrothermal molybdenum deposit.
