摘　　要：西沟钼矿位于河南省汝阳县境内,地处东秦岭-大别山钼成矿带的中段北侧,区内岩浆活动强烈而频繁,中-酸性火山岩分布较广,在该区已发现多处铅锌、钼矿床及矿点Mo资源量达20万吨,笔者通过对该矿床矿体特征、控矿地质条件、地球化学、地球物理等特征的分析研究,总结矿床成因和区内主要控矿因素,为在该区寻找铅锌钼等多金属"盲矿体"具有一定的指导意义。Xigou molybdenum in Ruyang county of Henan Province, is located in the north of the middle part of the east Qinling-Dabie mountain molybdenum metallogenic belt. Magmatic activity in the area is strong and frequent. Intermediate-acid volcanic rocks are widely distributed. We have found many lead zinc and molybdenum deposits in this area. By analyzing and studying the characteristics of the ore body, ore-controlling geological conditions, geochemistry and geophysics of the deposit, the author summarizes the genesis of the deposit and the main ore-controlling factors in the area. And it has certain guiding significance for the search of lead-zn-molybdenum polymetallic "blind ore body" in this area.
