摘　　要：文章对松辽盆地西南部白兴吐地段姚家组成矿条件进行了分析,包括姚家组辫状河相灰色砂体特征、后生还原及后生氧化作用特征、铀矿化异常特征、铀矿化异常与断裂的关系、铀矿化异常与层间氧化的关系、铀矿化成因及控制因素等。据此认为,白兴吐剥蚀天窗东缘白兴吐-东哈根地段存在有利的铀成矿条件,具有发现钱家店类型铀矿床的前景。The paper mainly analyes the uranium mineralization conditions at Baixingtu distric of southwestern Songliao basin. The research is focused on the characteristic of braided stream faces grey sandbody of Yaojia formation and the feature of epigenetic deoxidation and oxidization features of uranium mineralization abnormity, relation of uranium mineralization abnormity to fault, relation of uranium mineralization abnormity to interval oxidation, genysis of uranium mineralization and their controlling factors. It is considered that there are favorable metallogenic conditions in the Baixingtu-Donghuagen district of the east edge of Baixingtu denuded structure window for the formation of Qianjiadian type uranium deposit.
