The Dingshan area, located in the northern Junggar Basin, is a significant prospecting area for sandstone-type uranium deposits. Field investigation and interpretation of remote-sensing images show that Cenozoic tectonic movement in this area is characterized by reactivation of deep thrust-faults, resulting in extensional fractures and formation of large billabongs at the surface. Measurement of slickensides and joints indicates that there are at least two stages of new tectonic movement during the Late Cenozoic. The tectonic evolution process during the Cenozoic is, therefore, reconstructed based on sedimentary filling features and neotectonic movement, and the Sangequan block is suggested as a favorable metallogenic area for sandstone-type uranium deposit.
