陕西丹凤地区资峪沟伟晶岩铷矿赋存状态

摘要

介绍了丹凤地区花岗伟晶岩脉中铷矿矿石特征、岩石化学成分，分析了铷元素在矿石中的赋存状态，采用一系列矿物学（电子探针波谱及能谱分析）和地球化学（元素相关性计算）方法进行分析计算，结果表明：矿石中铷与钾元素铷与钾关系密切，主要赋存于含钾矿物的钾长石和云母中，铷的载体矿物为钾长石、白云母、黑云母等。%The ore characteristics and chemical compositions of rock mass of the rubidium mine in pegmatite veins are introduced in detail,the occurrence state of Rb in the ores is researched,a series of mineralogy(electron probe spectrum and energy spectrum analysis)and geochemical(elemental correlation calculation)method are used to conduct analysis and calculation.The results show that:rubidium and po-tassium in ores are closely associated with each other,they are mainly distributed in potassium feldspar and mica that are containing potassium minerals,rubidium carrier mineral are potassium feldspar,musco-vite and biotite.
