摘要 蛇岭地区位于下庄矿田东北部江西省境内。区内地层出露有震旦—寒武系浅变质岩系,主要出露燕山期花岗岩,基性岩脉呈岩墙产出。区内断裂构造十分发育,主要有NNE向、NEE向、NW向和EW向4组构造,控制了铀矿体(化)的空间展布。区内分布有蛇岭矿床(由307、308、617矿点组成),以及410、310、105矿点,铀矿化主要产于燕山期细不等粒白云母花岗岩和中粗粒似斑状黑云母花岗岩中,受断裂构造、花岗岩体、基性岩脉和部分受不整合面联合控制。结合该区地质工作成果,详细分析了区内铀成矿地质特征,总结了控矿因素,探讨了蛇岭矿床(307、308、617矿点)以及410、310、105矿点的找矿方向,供区内后续找矿工作参考。

Abstract: Sheling Area is located in the northeastern Jiangxi Province of Xiazhuang Ore Field.In the stratum of the area,there is a series of Sinian-Cambrian metamorphic rocks,mainly revealing Yanshanian granites.The basic dykes are occurred by rock walls,and the fault structures are well developed,four structures such as NNE-trending,NEE-trending,NW-trending and EW-trending structures are developed in the area,the spatial distribution of uraniummineralized) orebodies are controlled by them.Sheling Uranium Depositconsist of 307,308 and 617 mineral occurrence) and 410,310 and 105 mineral occurrence are distributed in the area.The uranium mineralization is mainly occurred in Yanshanian fine unequal muscovite granites and medium coarse-grained porphyritic biotite granites.The uraniummineralized) orebodies are jointly controlled by fault structures,granite bodies,basic dykes and partial unconformity tectonic surface.Based on the geological results of the area,the uranium metallogenic geological characteristics and ore-controlling factors are discussed,besides that,the prospecting directions of Sheling Uranium Depositconsist of 307,308 and 617 mineral occurrence) and 410,310,and 105 mineral occurrence are stduied,so as to provide some reliable reference for the further uranium deposit prospecting work in Sheling Area.
