摘　　要：文章在前人对伊犁盆地南缘砂岩型铀矿成矿条件、成矿规律以及控矿因素等方面的研究认识基础上，结合最新勘查工作进展，对该地区的砂岩型铀矿成矿模式作了进一步深化，提出伊犁盆地南缘铀成矿具有中西段稳定斜坡带继承性叠加富集成矿、中东段强构造改造背景下叠加改造成矿的特点。基于这一认识，提出了今后的找矿方向。Based on the previous research results in metallogenic environment,metallogenic regularities, ore controlling factors and latest exploration progress of sandstone type uranium deposits in the southern margin of Yili basin,metallogenic model was improved in this paper.According to the model, uranium mineralization in the mid west segments was inherited,superimposed and enriched where is a stable slope,and mineralization in mid east segments was in reworking progress where the structure setting is of strong reformation.Finally,the future prospecting orientation was put forward.
