| 摘 要： | 以产于碎斑流纹岩中的铀矿化蚀变为例,对居隆庵铀矿床蚀变分带及其地球化学特征进行了系统研究,将该区蚀变分成5个带。地球化学研究表明,围岩蚀变过程中元素迁移、富集有明显的规律;常量元素（Ca、Mg、K、S）、微量元素（Cu、Pb、Zn、As、Sb、Th、Mo、W、F）和稀土元素（REE）有明显富集;亲硫元素是铀成矿作用的指示元素;成矿过程至少经历了两次热液活动;成矿流体具有还原性和深源性。

| Abstract: | Uranium mineralization in porphyry rhyolite of Julongan deposit was systematically studied in the alteration zoning and its geochemical characteristics.The alteration can be divided in five zones.The values of maijor elements Ca,Mg,K and trace elements Cu,Pb,Zn,As,Sb,Th,Mo,W,F,S and REE have been increased in mineralization process.The metallogenic fluids was reductive fluids and may have deeply-derived origin. |
