| 摘 要： | 热水沉积硅质岩对于矿床研究具有重要意义.通过对硅质岩的岩石学及常量元素、稀土元素等地球化学特征的研究,认为矿区硅质岩属于热水沉积成因,形成于浅海-大陆边缘环境.结合矿床地质特征,认为矿床早期存在热水喷流沉积成岩成矿作用,在矿源岩阶段形成了金的初步富集.硅质岩的空间分布规律具有找矿标志的意义,为金山金矿的进一步找矿工作开辟新的思路.

| Abstract: | Hydrothermal sedimentary silicalite studies are important for ore deposits. Based on comprehensive petrological and geochemistry characteristics of major elements, REE, etc, origin of silicalites is hydrothermal sedimentation in the Jinshan gold deposit. Silicalites were formed in epeiric sea or continental margin environment. Combining with ore deposit setting, it is suggested that there is a later hydrothermal exhalative mineralization in the Jinshan gold deposit, which made up the mine source rocks. Furthermore, silicalites are important exploration indicator and it open a new thinking way for exploration. |
