| 摘 要： | 显微镜下矿石薄片鉴定和铀矿物电子探针分析显示,白兴吐铀矿床发育高岭石化、碳酸盐化、黄铁矿化、水云母-绢云母化和赤铁矿化等中低温热液蚀变;矿石的铀矿物主要为铀石,少量沥青铀矿,以及部分含钛铀矿物,矿石普遍富含磷和钛。铀矿物与热液成因的胶状、团块状和莓状黄铁矿、铁白云石、赤铁矿等共生。这些特征表明,该矿床的工业铀矿化与热液作用关系密切。

| Abstract: | Thin section feature and electronic probe analysis of rocks show that middle-low temperature hydrothermal alteration has been developed in Baixintu uranium deposit,the alteration includes kaolinization,carbonatation,pyritization,hydromicazation,sericitization,hematization et.al.The uranium mineral of ore is maily coffinite,a little pitchblende and titanous uranium mineral and the ore is generally rich in phosphorus and titanium.Because uranium mineral coexists with colloidal,clumpy and fragiform pyrite and ... |
