| 摘 要： | 本文以J4隐爆角砾岩体为重点研究对象,从矿床地质、热液蚀变等方面进行分析研究,认为金矿床的形成与浅成-超浅成酸性斑岩侵入体有着密切的成生联系;通过宏观及镜下观察并综合各类蚀变矿物组合之间的关系表明,热液蚀变与金成矿关系密切,蚀变在水平方向及垂直方向上具有分带性。一般而言,在垂直方向上,自岩体中心向上、向下对称分布为：石...

| Abstract: | The geological feature and hydrothermal alteration characteristics of J4 breccia,Qiyugou area,Henan province,is investigated to reveal the close relationship between gold mineralization and intrusion of hypabyssal-superficial felsic porphyry.The paragenetic association of alterated minerals indicates that alteration zones are vertical to the intrusion： from the center to the outer margin lays from quartz-orthoclase zone,to quartz-biotite zone,and to propylitization.The industrial ore-bodies are mainly occurred to the contact area of quartz-orthoclase zone and quartz-biotite zone. |
