摘要
邬郁盆地是西藏自治区最新发现的产铀盆地,深入研究该铀矿的可地浸条件对指明本区后期的找矿类型方向等勘查工作具有重要的指导意义。在阐述邬郁盆地区域地质背景和砂岩型铀矿特征的基础上,对矿体地质特征和水文地质特征进行了分析。通过与砂岩型铀矿床地浸评价参数进行对比研究,认为该地区砂岩型铀矿的可地浸条件较差。研究区东部嘎扎村组中段砂体基本不具备可地浸砂岩型铀矿条件;研究区中西部宗当村组下段砂体具备一定的可地浸条件,但还需要后期工作进行验证和研究。
Wuyu basin is the latest discovered uranium-existing basin in Tibet. In-depth study of uranium occurrence has important guiding significance for the type of prospecting and range of reconnaissance in following exploration in this area. Based on expounding of the regional geological background and characteristics of sandstone type uranium deposit in Wuyu Basin, the geological and hydrogeological characteristics of ore-body are analyzed. By comparing with the in-situ leaching evaluation parameters of sandstone type uranium deposit, the in-situ leaching conditions of sandstone type uranium deposits in this area are considered to be poor. The Middle Section sand body of the Gazhacun formation in the eastern part of the study area doesn＇ t have in-situ leaching Conditions. The Lower Section Sand body of the Zongdangcun formation in the center-west part of the study area has certain in-situ leaching conditions. But it still need to be validated and researched in follow-on work.
