诸广山岩体南部铀矿床某些元素的分布特征及其与铀矿体的关系

The Distributing Characteristics of Some Chemical Elements of the Uranium Deposits in the South of Zhuguang Granites and It's Relationships with the Uranium Ore Bodies

诸广山岩体是我国铀矿的重要产地,是个找矿远景广阔、难度大的富铀岩体,很有必要进行攻深找盲。以诸广山岩体南部三个主要矿床的原生样为代表进行综合整理、分析、研究,探讨了区内铀矿体与微量元素在空间上的分布关系及其成生关系。研究结果表明,利用某些微量元素的分布特征是寻找和揭露隐伏矿体的一个重要环节;成矿热液来源与岩浆分离有关,热液来源具有深源特征;亲硫元素的富集对铀的富集沉淀有一定的聚集作用,而且铀含量高低与硫的含量密切相关。在区内通过查明微量元素异常与铀矿化的关系,总结其分布特征和成矿规律,对深部铀矿体的揭露有较好的指示作用。

The Zhuguang granites are important habitat of the uranium deposits in China,which are rich and have big prospective resources and full of difficulties.It is necessary to explore deeply and find the hidden ore body.Discussing about the space and causes relationships of uranium ore bodies and microelements by sorting,analysising and researching the primary samples of three main uranium deposits in the south of Zhuguang granites.The results express that it is an important part of finding and exposing the blind ore bodies to make use of the distributing characteristics of some chemical elemenst;hydrothermal sources are related to magmatic differentiation and have deep-source characteristics;enrichment of sulphophile elements have an effect on enrichment and precipitation of uranium,the uranium＇ content is closely related to the sulphur＇ content.It is useful to expose the deep uranium ore bodies by finding out relationships of microelements＇ anomalism and uraniums＇ mineralization,summing up the distributing characteristics and rules of mineralization.
