沙子江铀矿床大地构造位置处于扬子板块与华夏板块结合部位,苗儿山复式岩体中段,NNE向新资走滑断裂上盘。目前,新一轮的普查工作在其外围取得了喜人的成果,显示了该地区具较大找矿潜力,值得重视。本文试图探讨沙子江铀矿床铀成矿作用,以便对矿床成因以及周边找矿工作抛砖引玉。1区域铀成矿条件1.1岩体特征
The geotectonic location of the sandstone-hosted uranium deposit is located at the junction of the Yangtze Plate and the Huaxia Plate and the middle part of the Miaolianshan complex rock mass, with the NNE heading toward the Xinzisui-slippery fracture upper plate. At present, a new round of census work has made gratifying achievements on its periphery, which shows that there is a great prospecting potential in the region and deserves attention. This paper attempts to explore the uranium metallogenic process of the Shazijiang uranium deposit in order to initiate the work on the genesis of the deposit and the surrounding ore prospecting. 1 Uranium metallogenic conditions 1.1 Rock mass characteristics
