| 摘 要： | 大兴安岭火山岩区金矿的找矿突破是90年代后期实现的,目前发现的类型有HS型、LS型及硅化石英脉型3种浅成低温热液矿床.四五牧场金矿是产于海拉尔-根河中生代火山岩盆地边缘的HS型浅成低温热液金矿床,其形成与隐爆角砾岩体关系密切,隐爆角砾岩体的产出明显受构造控制并具成群分布的特点.岩石蚀变为典型的酸性硫酸盐型石英-高岭石(迪开石)-明矾石蚀变矿物组合.

| Abstract: | In recent years, some gold deposits have been discovered in the Daxing'anling volcanic rock regions. Gold deposits can be divided into high sulfidation, low sulfidation and silicification quartz vein types. Siwumuchang gold deposit is a high sulfidation type epithermal gold deposit, which occur on the margin of the Haila'er-Genhe Cretaceous volcanic basin. The metallogenesis is relate to the breccia that controlled by fault. Wallrock alteration association is quartz-dickite-alunite. |
