摘　　要：墨斗河钼多金属矿是斑岩-夕卡岩-脉型"三位一体"复合型矿床,位于豫南大别山北麓新县境内,地处东秦岭—大别钼成矿带的东段。矿区岩浆活动频繁,经历了不同期次的区域变质作用。矿区出露地层主要为古元古界七角山组和新元古界苏家河群浒湾组。文章根据区域地质背景、矿区地质特征,综合研究了墨斗河钼多金属矿床的成矿信息、成矿地质环境和化探异常特征,认为矿区钼矿成矿条件优越,找矿潜力较大,预测矿区南部及深部可能存在大型斑岩型钼矿体。Modouhe Mo-polymetallic deposit is a complex ore deposit of porphyry, skarn and vein type ofores located at north side of Dabie mountain in the middle of East Qinling-Dabie Mo ore belt. The ore deposit area is exposed to multi-staged regional metamorphism with frequent magmatism. Palaeo-proterozoic stata of Qijiaoshan formation and Neo proterozoic strata of Huwan formation of Sujiahe group are ex posed. Based on regional geological setting, geological feature of the ore deposit area, comprehensive met allogenic environment and geochemical anomly characteristics we think that the ore deposit area is superior in metallogenic condition with tremendous prospecting potentiality. It is predicted that big porphyry mo lybdenum ore body may occur to depth of the deposit.
