| 摘 要： | 以芨岭地区铀矿床碱交代蚀变岩石为研究对象,对该区碱交代作用蚀变的特征进行详细研究。结果表明:芨岭钠交代岩型铀矿床属断裂碱交代型铀矿床,矿床蚀变种类繁多,主要有钠长石化、绿泥石化、碳酸盐化、赤铁矿化、绢云母化和硅化等。蚀变组合及分布特征较明显,并与铀矿化关系密切。

| Abstract: | Based on alkali metasomatism and alteration rocks in uranium deposit in Jiling area, the authors studied in details the alkali metasomatism and alteration characteristics in the study area. It was concluded that Jiling sodium metasomatic type uranium deposit be- longed to a uranium deposit of fracture alkali metasomatism with varied altered types like albitization, chloritization, carbonation, he- matitization, sericitization and silicification. The alteration composition and distribution characteristics were clear and closely related with uranium mineralization. |
