吐哈盆地十红滩铀矿床控矿因素及找矿靶区研究

在分析了吐哈盆地十红滩铀矿床地质构造、含矿地层和水动力环境对层间氧化带和铀矿化控制作用的基础上, 笔者认为艾丁湖构造斜坡带、断块构造及次级断裂、褶皱是铀矿化定位的标志, 辫状河相砂体为层间氧化带和铀矿化提供了有利的空间, 层间承压水和地球化学环境的变异部位是成矿物质沉淀的重要场所, 据此对有利的成矿靶区进行了预测。

Research on ore-controlling factors and prospecting targets in Shihongtan uranium deposit area,Turpan-Hami basin

Based on analyzing the controlling role of geologic structure,host formation and hydrodynamic environments on interlayer oxidation zone and uranium mineralization,the author suggests that the Aiding structural slope,block-faulting structure,and subsidiary faults and folds are indications of uranium mineralization emplacement,sand bodies of braided stream facies provide favorable space for the development of interlayer oxidation zone and uranium mineralization,and variation sites of interlayer artesian water and geochemical environments are important places for the precipitation of ore material.Based on the above-mentioned a prediction of favorable metllogenic targets is made.
