摘要:
提要:通过对近几年来十红滩地区铀矿勘查资料及找矿成果的综合研究,系统阐述了吐哈盆地西南缘十红滩矿床的地质构造、含矿岩系沉积环境、砂体分布、层间氧化带发育特征等铀成矿条件,对矿区南、北矿带控矿层间氧化带分带性、矿体形态、规模、空间展布、铀存在形式、成矿年龄及铀成矿规律进行了详细研究。进一步总结了区域砂岩型铀成矿条件和找矿前景,指出吐哈盆地西南缘随着找矿工作进展可望成为大型地浸砂岩型铀资源基地,并对指导天山造山带及类似地区地浸砂岩型铀矿找矿具有重要意义。

Abstract:
Abstract:Through an integrated study of the data of uranium prospecting and exploration of the Shihongtan area in recent years, the paper systematically deals with the conditions of uranium deposit formation, such as the geological structure, depositional environment of ore-bearing rock series, distribution of sand bodies and development features of interlayer oxidation zones and also intensively studies the zoning of the ore-controlling interlayer oxidation zone, shapes, sizes and spatial distribution of orebodies, mode of occurrence of uranium, mineralization age and regularity of uranium mineralization. It further summarizes the regional formation conditions and ore prospects of sandstone-type uranium deposits. With progression of uranium prospecting, the southwestern margin of the Turpan-Hami basin is expected to become a large base of underground leaching sandstone-type uranium resources. This study has great significance for guiding prospecting for underground leaching sandstone-type uranium deposits in the Tianshan orogenic belt and similar areas.
