| Abstract: | 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. |
