摘要
盆地砂岩型铀矿区域评价的主要目的是初步划分环境带和圈定成矿有利地段,为下步较详细工作提供依据。其中水文地质工作着重从以下几个方面来进行:水文地质单元划分;承压含水系统和目的层的确定;水动力条件分析;水文地球化学环境分析;古水文地质分析;氧化还原带和成矿有利地段的圈定。
The main purpose of regional evaluation of uranium ore-formation is to preliminarily divide environmental zones and to delineate favourable areas for uranium ore-formation in order to provide basis for further detailed prospecting work.Of the various kinds of prospecting work,the hydrogeologic work should be mainly carried out in following aspects:division of hydrogeological units,the determination of artesian water-bearing system and the identification of prospecting target horizon;the analysis on hydrodynamic regime,the analysis on hydrogeochemical environments,the paleo-hydrogeologic analysis and the delineation of redox front and favourable area for uranium ore-formation.
