摘　　要：豫西矿集区以矿产种类多,规模大,分布密集为主要特征;可分为斑岩热液成矿系统、脉状钼矿成矿系统、火山热液成矿系统、浅成热液成矿系统、叠加改造成矿系统和陆相砂岩成矿系统六种。成矿系统时间结构显示,矿集区内存在元古代、印支、燕山期成矿作用,后期的成矿作用叠加到前期的成矿作用之上,形成叠加改造型矿床;成矿空间结构体现出受地幔亚热柱构造、地球化学块体和热点严格控制,各成矿系统的物质结构复杂,彼此显示出相似性、同源性,矿石矿物种类多,共(伴)生元素多样。豫西矿集区是在豫西地壳剧烈的、多期次的演化过程中形成的,成矿系统的时空结构与区域地壳演化历史十分吻合,其成矿机制上具有内在的密切联系。The western Henan ore deposits-clustered district is characterized by multi-mineral resources, large size and dense distribution of the ore deposits. The metallogenic system includes porphyry hydro- thermal, vein--type Mo, volcanic hydrothermal, epithermal, printing and reworking, and terrestrial sandstone, the 6 metallogenic systems. Temporarily metallogeny of Proterozoic, Hindo--china and Yans- hanian eras occur in the deposits-clustered district and the later overprinted on and reworked the former. Spatially the metallogenic systems are controlled by sub-mantle plume, geochemical block and hot spot showing complex ore materials but similarity and same source and multi-ore minerals and by-product ele- ments. The western Henan ore deposits--clustered district is exposed to intense crustal movement and ex- perienced multi-evolution. Temporarily and spatially the metollgenic systems are well coincided with the crustal evolution history of the west Henan province and the ore--forming mechanism internally connect-ed.
