摘　　要：重点论述白兴吐铀矿床预测的关键技术;提出了松辽盆地的东泛西超、北沉南隆的沉积构造演化格局的新观点及"辫状河道洼地-反转隆升剥蚀构造天窗-贯通性断裂——基性岩浆活动带"三位一体成矿理论,用多源复成因成矿理论重建了钱家店铀矿的成矿模式,并运用这一新的成矿理论模式,成功地预测了远景靶区,经生产部门深入勘查,落实了白兴吐铀矿床。This article focuses on the key techniques for the prediction process of Baixingtu uranium deposit. New viewpoints of sedimentary evolution pattern as ＂west flood caused overlap in East, and north subsidence while south uplift＂ are proposed in Songliao Basin. The deposit is controlled by braided channel depression, reversal uplifted structural window and marie related fracture zone, and the metallogenic model as ＂three ore-forming condition in one place＂ for Qianjiadian uranium deposit is rebuilt with multi-source and polygenetic theory. With this new metallogenic model, Baixingtu uranium deposit has been successfully predicted and made a breakthrough in Songliao Basin for the exploration of sandstone type uranium deposits.
