摘要
龙巴岭铀矿床矿化类型不同于相山铀矿田已知的水云母-萤石型和钠长石型铀矿化类型,它以石英-晶质铀矿矿物群产于碎斑流纹岩中。根据铀矿化产出形式、矿化岩石的化学组成和矿物群的组成及生成顺序,这种铀矿化类型既区别于已知的铀矿化类型,又与这两种铀矿化类型存在某些关联。介绍这种矿化类型可能会有益于对相山铀矿田的铀成矿认识和找矿评价。
It is different to the known hydromica-fluorite type and albite type uranium mineralization type,Longbaling uranium deposit occurs in porphyroclastic rhyolite as the mineral group of quartz-uraninite.According to the occurrence forms,chemical compositions of mineralized rock and compositions and forming sequences of the mineral groups,the mineralization type is different from the known uranium mineralization type,but is related to two uranium mineralization types to some degrees.Introduction to this type of mineralization may be helpful to understand the mineralization and prospecting evaluation in Xiangshan uranium ore field.
