摘要
根据钼矿床的成因、控矿构造、矿石成分及结构构造等，把东秦岭钼矿床分为2组七大类：斑岩-角砾岩型矿床、矽卡岩型矿床、斑岩-矽卡岩型矿床；破碎带蚀变岩型矿床、石英脉型矿床、韧性剪切带型矿床和碳酸盐脉型矿床。脉型钼矿的发现，丰富了河南省内钼矿的类型。从中选取有代表性的进行了成矿地质特征论述，进一步阐明了成矿时代，东秦岭钼矿的成矿年龄从1884±210—106．89±2．14Ma。
According to the genesis of molybdenum deposits, controlling structure, mineral composition and ore frame, Dong qinling molybdenum deposit was classified into seven major types： porphyry -breccia -type deposits, skarn - type deposits, porphyry - skarn deposit; broken with altered rock type deposit, quartz vein - type deposits, ductile shear zone - type deposits and carbonate vein - type deposit. The discovery of vein - type molybdenum mine in Henan province enriched the types of molybdenum. Some representative deposits were selected to he analyzed ore-forming geological characteristics, and the forming time was further clarified. The mineralogenetic epoch Dongqinling molybdenum deposits are from 1884 ± 210 Ma to 106.89 ± 2.14 Ma on of
