江西省九瑞地区金矿床类型、主要特征、成矿序列及控矿因素探讨

DISCUSSION ON GLD DEPOSIT TYPES, MAIN CHARACTERISTICS,MINEROGENETIC SEQUE-NCES AND ORE CONTROL FACTORS IN JIUJIANG-RUICHANG AREA,JIANGXI PROVINCE

摘要: 九瑞地区是江西重要的内生金属成矿区之一。本文综合分析了近年来区内找矿科研工作的资料;划分了区内金矿的类型、成矿序列;简述了主要类型代表性矿床的地质特征。在此基础上探讨了区内地层、构造、岩浆岩对金矿的控制作用及时间上的分布规律,指出工志留纪、泥盆纪、石炭纪和二叠纪为金矿成矿的预基期,侏罗纪、白垩纪为主导期,第四纪为改造期,以及在各个时期金的成矿作用各具特色、渐次叠加发展、富集的规律。
