摘要
银山多金属矿床的形成经历了构造动力热液成矿及火山-岩浆热液成矿两个阶段。构造动力热液成矿奠定了银山矿床矿化的基本格局,火山-岩浆热液成矿作用叠加其上,形成了银山大型或特大型金铜多金属矿床。大量事实表明,两种成矿作用在时间上具同期性,构造动力热液成矿稍早些。在空间和成因上两者密切相关,它们构成了构造动力-火山岩浆同步一体的成矿体系。
The formation of Yinshan Au-Cu polymetallic ore deposit underwent two metallogenic stages: tectono-dynamic hydrothermal metallization and volcano-magmatic hydrothermal metallization.A lot of geological facts indicate clearly that these two kinds of metallogenesis are basically contemporaneous in time, but the volcano-magmatic metallization is slightly late and it superimposed on the tectono-dynamic metallogenesis. Two kinds of metallogenese are close-ly correlative with each other in space and in origin, they constitute a tectono-dynamic-volcano-magmatic metallogenic system.
