| 摘 要： | 银山矿区的三个旋回火山一次火山岩属同源产物,其原始物质的35%为沉积岩熔体和65%为玄武岩质熔依.是两者的混岩浆.因而.岩石的成因类型属幔壳混合型.根据矿床中蚀变围岩千枚岩的希土组成特征、认为不同矿化蚀变带稀土分配形式基本相似,从而揭示了各带成矿流体成因上的继承性和来源的一致性.

| Abstract: | On the basis of the study on REE litho geochemistry, it is considered that three major cycles of Yanshanian volcanic-subvolcanic rocks would be of isogenous rock association. Their primive material is the migma of sedimentary rock melt (35%) and basaltic melt (65%) . The genetic Type of these rocks belongs to crust-mantal mixture ones. The study of the characteristics of REE composition on the altered country rock indicates that the REE distribution patterns of different mineralization and alteration zones arc similar. It implies that the ore-forming fluids of different zones in this region are inheritance in genesis and accordance in source. |
