| 摘 要： | 文章阐述了新疆白杨河铀铍矿床的近矿围岩蚀变特征,指出与矿化关系密切的围岩蚀变主要是赤铁矿化和萤石化。矿床岩石地球化学分析结果表明,靠近矿化中心带蚀变岩石的SiO2含量降低,而CaO、MgO的含量升高;Pb、Mo和Sb等元素含量与铀矿化具有正相关性,是该矿床铀富集的良好指示性标志。

| Abstract: | This paper studied the alteration characteristics of near ore wall rocks in Baiyanghe uranium and beryllium deposit,Xinjiang.It was found that the main wallrock alteration is hematitization and fluoritization.Geochemical analysis result of rocks from the deposit suggested that near the central zone of mineralization,the content of silicate decreased while the concents of Ca and Mg increased,the content of Pb,Mo,Sb correlate positively with uranium content and therefore they can be used as the indicators for... |
