摘要
曲源铀矿床位于赣杭构造火山岩铀成矿带南西段,产于紫云山花岗岩岩株与玉华山火山盆地接触带的复式花岗岩内部,矿床的形成与燕山早期花岗岩关系密切。断裂构造、碱交代蚀变岩对铀矿化控制作用十分显著,矿化产出形式分为构造角砾岩(花岗岩脉)型、碱交代蚀变岩型2类。通过梳理已有勘查资料,阐释了区域成矿地质背景和矿床地质特征,总结了控矿因素及矿体分布规律。在评估勘查程度的基础上,运用铀成矿新理论,并结合近年来的找矿工作成果,认为曲源铀矿床深部及外围具有优越成矿条件和找矿潜力,提出了下一步的找矿方向。
The Quyuan uranium deposit is located in the southwestern part of the Ganhang tectonic volcanic uranium metallogenic belt.It is produced inside the complex granite which is located in the contact zone of the Ziyunshan granite dike and the Yuhuashan volcanic basin.Its formation is closely related to the early Yanshanian granite.The fracture structure and the alkali metasomatic alteration rock have a significant effect on the control of uranium mineralization.The mineralization output form is divided into two types:tectonic breccia(granite vein)type and alkali metasomatic alteration rock type.By studying the existing exploration data,the regional metallogenic geological background and the geological characteristics of the deposit are explained,and the ore-controlling factors and ore body distribution are summarized.On the basis of assessing the degree of exploration,using the new theory of uranium mineralization and the achievements of recent prospecting,it is believed that the deep and peripheral parts of the Quyuan uranium deposit have favorable metallogenic conditions and great prospecting potential,and the next direction of prospecting is proposed.
