摘　　要：位于河南省灵宝市朱阳镇境内银家沟硫铁多金属矿床是一个拥有Cu、Au、S、Fe、Mo、Pb、Zn多种成矿元素的独立工业矿床,且各具一定规模。通过对该矿床、矿体地质特征及成矿地质条件分析研究,认为该矿床受矿源层官道口群龙家园组和巡检司组白云岩,多组断裂构造交汇部位,燕山期花岗斑岩体及其接触带构造联合控制,属斑岩-矽卡岩型矿床。在这一认识基础上总结了找矿标志及找矿方向。Yinjiagou Pyrite-polymetallic deposit, located in Lingbao City, Hena Province, is a independent industry deposit containing Cu,Au, S,Fe,Mo,Pb,Zn chemical elements. According to the study on the orebody geological characters and metallogenic geological conditions, the deposit is controlled by the of source bed （dolomite of Longjiayuan and Xunjiansi Fm. of Guandaokou Group）, intersection of faults and the contact zone between Yanshan granite-porphyry and the dolomite. It belongs to porphyry-skarn type deposit. Based on the roles above, ore-prospecting suggestion is made out for the nest work.
