| 摘 要： | 金丰度对矿床形成的意义是值得深入研究的课题。世界上多数金矿与变质岩有关,但在事实上,后者的金丰度并不是很高。金厂峪矿区变质岩金丰度亦较低,作为金矿围岩的斜长角闪岩中的金仅为3.1ppb,但是金的“易溶性”是所有与金矿有关岩石中最好的。这就使它易于在适当的成矿条件下活化、迁移和富集成矿。因此,斜长角闪岩应是金矿的最佳矿源层。

| Abstract: | The significance of gold abundance in the formation of gold deposits is a subject worthy of further study. Most gold deposits in the world relate to metamor-phic rocks, but in fact, the gold abundance of these rocks is not so high. Metamor-phic rocks in Jinchangyu district is also low in gold abundance. Amphibolites which are host rocks of the deposits have only 3.1 ppb gold, but the "dissoluble property" of gold in amphibolite is the best among the rocks related to gold-ore deposits, this enables the gold easy to activate, migrate and enrich under suitable metallogenic conditions. Therefore, amphibolites should be the best source rocks of the deposit. |
