赣南均田铀矿床成矿作用及找矿方向

Uranium Mineralization and Prospecting Direction of Juntian Uranium Deposit in South Jiangxi

均田矿床位于桃山—诸广铀成矿带中段,马岭复式岩体北端。通过系统阐述矿床区域地质背景、成矿地质条件及矿化特征,梳理近年来的勘查找矿成果,对矿床铀成矿作用展开了分析和探讨。围绕矿床成矿物质来源、构造及中基性岩脉与成矿的关系,初步形成了矿床的铀成矿模式。认为在寻找现有花岗岩外带型铀矿的同时,岩体内部隐伏断裂及中基性岩脉发育处可作为矿床进一步勘查找矿方向。

Juntian uranium deposit is located at the middle of the Taoshan-Zhuguang uranium mineralization belt and the northern of Maling granite mass. Through systematic exposition the regional geological background, metallogenie geological conditions and characteristics of mineralization, and reviewing the prospecting results in recent years, uranium mineralization in the deposit has been analyzed and discussed. Around the mineral source of the deposit, and relationships between fault, intermediate-basic dike with mineralization, the uranium metallogenic model of the deposit has been formed. Based on the above results, it is considered that while searching for the granite take-out type of uranium mineralization, the concealed faults and intermediate-basic dike in the rock masses can be used as the prospecting direction for further exploration of the deposits.
