| 中文摘要: |
| 文章对豫西矿集区成矿类型进行了划分，归纳为3大类6个成矿类型。对岩浆热液叠加改造型矿床定义、成矿地质背景、构造转换与成矿进行了阐述，并通过对上宫金矿的矿石矿物共生组合、矿化蚀变特征、同位素地质特征研究，认为岩浆热液叠加改造型矿床赋矿地层古老，经历了长期的构造演化；成矿物质多种来源，具深源特性和造山带物质的痕迹；矿石的物质组成复杂，矿物共生组合种类繁多；成矿围岩遭受了强烈的变质、蚀变作用，蚀变岩石类型较多，矿化多期次叠加；具有多成因性。 |
| 英文摘要: |
| Ore deposits in clustered ore deposit area in western Henan province are divided into three types and 6 sub-types. Magmatic hydrothermally overprinted and reworked deposit is defined and its geological background, structural transformation and metallogeny expounded. According to researches on ore mineral association, mineralization-alteration characteristics and isotopic age data of Shanggong gold deposit the magmatic hydrothermally overprinted and reworked deposit is characterized by old hosting rock, long tectonic evolution, milt-ore material sources (from deep and orogenic belt), complex ore materials, various mineral associations, and strong metamorphjism of the host rock, multi-alterations and altered rocks, multi-staged and overprinted mineralization and multi-genesis.. |
