诸广山岩体南部铀矿成矿特征

诸广山岩体南部是我国铀矿产的重要聚集地,文章从阐明决定该区铀矿床形成的有关地质因素入手,对诸广山岩体南部的四个铀矿田的矿床、矿体、矿点进行对比,分析其同位素年龄、矿体标高、物质成分、平均品位等方面的异同,找出不同地段的矿床特征差异和变化规律,总结铀成矿特征。研究认为诸广山岩体南部具有较好的成矿、控矿条件,是较好的产铀岩体。通过研究铀成矿单元、铀成矿条件的差异,综合物化探成果和以往工作程度,并进一步查明地质背景和加强对深部信息的分析、研究,可为下一步针对不同成矿前景的有利地区进行分类预测提供依据。

Mineralization Characteristics of Uranium Deposits in Southern Zhuguangshan Granites

The south of Zhuguangshan granite is the famous metallogenic belt for uranium deposits. The article first focus on the key geological factors, such as the mineralization feature, ore-bodies occurrence, mineralization age, ore mineral compositions and average grade, etc., which are used for summarize the metallogenic regularity of those granite-related uranium deposits. The result shows that the south of Zhuguangshan granite area is a favorable place for uranium mineralization, and the prospecting work may be fruitful in the future.
