摘　　要：布雅盆地是塔里木盆地南缘有利的铀成矿地段。在简析布雅盆地区域地质背景、已知铀矿化特征的基础上,着重宏观地分析了盆地形成铀矿化的地层、构造、水文地质及铀源等条件,以构造为主线初步总结出该区铀成矿的载体形成、初始铀富集、相对停滞和破坏及叠加富集4个阶段,独特的构造演化促成了铀矿化的形成。Buya Basin is a favourable ore-formation zone located on the southern margin of Tarim Basin. Based on the concise analysis on the regional geological background and the known uranium mineralization features, the uranium forming conditions （such as strata, structure, hydrogeology and uranium sources）in this basin are analyzed emphathetically from the macroscopic point of view. Four stages of uranium formation in the area are preliminarily summarized with the structure as the thread, i.e. formation of uranium carrier, initial uranium enrichment, relative stagnance and superposition and enrichment. Unique structural evolution facilitates the formation of mineralization.
