十红滩铀矿床首采段矿床地质、地球化学特征

本简述了吐哈盆地十红滩铀矿床的区域、矿区地质特征，重点对矿区、首采段层间氧化带空间展布规模、分带性、前锋与铀矿化的关系做了研究；对首采段含矿砂体的空间分布、结构构造特征和铀矿体的展布规律、形态特征、厚度在空间上的变化情况以及铀矿石物质组分、铀存在形式等作了分析。在此基础上，总结了赋矿位置及矿床主要控制因素。

Geological and geochemical characteristics of section first to be mined,Shihongtan uranium deposit,Turpan-Hami basin

This article briefly introduces the regional geology,the geology of ore district with emphasis on the study of the spatial distribution,scale,zonation and the relation of roll front of interlayer oxidation zone to the uranium mineralization of the section first to be mined at the uranium ore district,Shihongtan uranium deposit,and analyses the spatial distribution,the structure and texture of ore hosting sand bodies,the distribution,the shape,thickness and their variation,as well as the composition of uranium ores and existense form of uranium in ores.On the basis of the above study the ore hosting position and main ore controlling factors of the deposit have been summarized.
