摘要
从岩体特征、构造条件、围岩蚀变、矿石物质成分等方面总结纳米比亚欢乐谷地区铀成矿特征,剖析铀矿化成因。在此基础上开展铀成矿条件分析,认为该区具有铀源丰富、构造发育、热源充足、蚀变强烈4个有利成矿条件。中部褶皱构造发育区找矿前景最好,是本区下一步白岗岩型铀矿找矿的重点地段。
Metallogenic features of uranium deposits in Happy Valley region of Namibia are summarized from the aspects of intrusive rocks,structure,wall rock alteration,ore composition,etc.,and the genesis of the uranium mineralization is analyzed.Then uranium metallogenic conditions are studied,and Happy Valley region is believed to be favorable for uranium metallization with rich uranium background,well-developed structures,plentiful heat sources,and intensive alterations.The central folded area is believed to be the most promising target for the prospecting of alaskite-type uranium deposits.
