摘要
十红滩铀矿床是我国北方重要的层间氧化砂岩型铀矿床,其产于吐哈盆地南缘艾丁湖斜坡带上。近几年的勘查发现,以十红滩背斜为界,东翼和西翼铀品位、平米铀量,矿体连续性以及矿体宽度均存在差异,即存在"东富西贫"现象。通过含矿含水层参数对比研究和地球化学组分的统计分析,认为铀源条件、水文地质、含矿砂体厚度、岩石还原容量、黏土矿物含量等在背斜东西两翼的差异性是造成这一结果的重要因素,提出在今后的扩大找矿过程中,应该加强不同地段以上参数的分析,其对于钻探工程部暑具有重要的指导意义。
Situated in the slope belt of Aiding Lake at the southern edge of the Turpan basin,Shihongtan uranium deposit, as one of the important interlayer oxidation sandstone type uranium deposit in north China. The recent survey found that there are different grade of uranium ore,uranium content per square meter, continuity of ore body, and breadth of ore body between the two flank of the belt which divided by the Shihongtan anticline. Thus, the deposit is rich in the east and poor in the west. Based on the comparative study on the parameters of ore-bearing aquifers and the statistical analysis of geochemical components, it is believed that this phenomenon is mainly attributed to the differences in such parameter as source of uranium, hydrological conditions, thickness of ore-bearing sandstone bodies, reduction capacity of rock, and mineral content of clay. Thus, it pointed out that these parameters should be carefully analyzed in different segment in the future process of expansive prospecting, which is of great significance to guiding the deployment of drilling engineering.
