摘　　要：本文以伊犁盆地地层及构造分布格局为背景,分析研究了盆地盆-山构造演化及流体演化与砂岩型铀矿的成矿关系,认为伊犁盆地砂岩型铀矿成矿存在铀的预富集、预演化及进一步演化、叠加富集等阶段。Based on the summary of strata and structure distribution of Yili basin, the relation of structure and fluid evolution to sandstone type uraium mineraliation are analyzed. It is found that uranium mineralization in Yili basin experienced ore hosting space forming, pre-alteration of hosting space, hosting space alteration and uranium formation stages.
