| 摘 要： | 本文在15个样品分析结果的基础上,论述赋矿火山岩中稀土及成矿元素地球化学特征,矿化火山岩中REE比非矿化火山岩中REE含量高;矿石中特别富集重稀土元素。矿石中主要共存元素是U,Th,Ti,Mo,Pb等。其中U,Th,Mo可以综合利用。成矿物质来源于硅铝壳,成矿元素的富集与岩浆分异作用有密切的关系。

| Abstract: | Geochemical characteristics of rare-earth elements and metallogenetic elements in the ore-bearing volcanics are discussed on the dasis of analytical results of 15 samples. The concentration of rare-earth elements is higher in mineralized volcanics than in unmineralized ones. The ores are especially rich in heavy rare-earth elements. Major compatible elements in the ores are U, Th, Mo, Pb etc., among which U, Th, Mo can be used. It was assumed that the metallogenetic materials might come from sialic crust and the concentration of metallogenic elements is closely related to magmatic differentiation. |
