| 摘 要： | 对玉山钨矿中酸性侵入岩进行岩石化学特征和稀土元素分析,岩石化学特征图解表明,玉山矿区侵入岩为S型花岗岩类,稀土元素分布模式表明玉山矿区岩浆岩为同源不同期岩体.综合地质特征分析,玉山矿区岩浆岩来自上地幔,在地壳深部岩浆房充分分异,成矿母岩浆沿大断裂运移上升,在接触界面下凹部位形成矽卡岩矿型白钨矿体,在围岩(碳酸盐岩)裂隙中形成脉状白钨矿脉.

| Abstract: | This article studies petrochemical characteristics and REE characteristics of the intermediate-acid intrusive rocks.The petrochemical characteristics diagrams indicate intrusive rocksare S-type granites,and REE patterns indicate the magmatic rocks are homologous but not contemporaneous.All above and the geological features indicate the mineralization mother rocks from the upper mantle are differentiated fully in the deep magma chamber,and the parental magmas forming transport and rise along the major faults... |
