Meso-Cenozoic sedimentary basins in northwestern China are superimposed composite basins starting with the extensional down-faulting prototype basin and then turning to compressional down-warping prototype basin. Based on the general law of Meso-Cenozoic tectonic evolution of northwestern China-two-time extensional down-faulting and two-time compressional uplifting-four stages of prototype basin evolution are classified. By analyzing characteristics of depositional systems and sedimentary facies developed in each stage of prototype basin evolution, authors emphasize that most favourable sand bodies for hosting uranium ores are those developed in the stage of extensional down-faulting prototype basin. In addition, six possible kinds of tectonic reworking pattern are discussed. It is proposed that the regional tilting occurring in the stage of compressional foreland prototype basin is the most advantageous for uranium ore-formation in sand bodies.
