摘要
下庄铀矿田是我国最大的花岗岩型铀矿田,本文在简要阐明下庄矿田区域地质背景的基础上,通过总结下庄矿田基础资料和前人的研究认识,得出目前下庄矿田铀矿化类型按控矿构造特征分为硅化带大脉型、"交点"型、密集裂隙带型、蚀变碎裂岩型、花岗岩外带型等五种,并对下庄矿田铀矿的物质来源、运移、富集成矿进行了初步探讨,对矿田内下步寻找更多、更富、更大规模的铀矿床有一定现实意义。
Xiazhuang Uranium Ore Field is the largest one of granite type in China. On the basis of brief description of areal geology background of Xiazhuang, by summing up the initial data of Xiazhuang and the the predecessors＇ study of it, this paper draws a conclusion that according to the characteristics of the ore-controlling structures, the uranium mineralization types in this ore field can be divided into five types, including silicified zone, intersection, spaced fissure zone, altered cataclastic rock, metamorphic types. Furthermore, primary discussion for the material source, transportation,enrichment and mineralization of uranium in Xiazhuang ore field was progressed, which have realistic significance for prospecting for more rich and large uranium deposit.
