赣南河草坑铀矿田控矿因素及找矿潜力分析

Ore controlling factors and prospecting potential analysis of Hecaokeng uranium ore field in southern Jiangxi province

文章在介绍河草坑铀矿田成矿地质背景的基础上,结合近些年开展的铀资源调查评价工作,对控矿因素进行了分析,并认为区内铀矿化主要受断裂构造、岩体、火山作用和蚀变带控制,区内铀矿化是构造-岩浆活动和热液蚀变共同作用的产物;提出了矿田南东部的龙骨千—仙坑地段、会昌红盆东缘深部和火山口及近外围铀成矿地质条件有利,找矿潜力大。

Based on the metallogenic background of Hecaokeng uranium orefield and the uranium resources survey and evaluation carried out in recent years are analyzed the ore controlling factors.It is considered that the uranium mineralization in the area is mainly controlled by fracture,rock mass,volcanism and alteration zone.The mineralization is the result of the interaction of tectonic magmatic activity and hydrothermal alteration by which Longguqian-Xiankeng section in east of the ore field,eastern margin of Huichang red basin and crater periphery arepoint out to be favorable and potential for formation of uranium ore.
