Abstract:During the Cenozoic,strong multi-stage tectonic events occurred in western China,which experienced a complex tectonic-geomorphic evolution history.Tectonic setting and geodynamic process determined the tectonic-geomorphic evolutions in the continent of western China.Sedimentary basin-orogen belt systems are the dominant basic structural pattern in western China during the Cenozoic.Basin-range pattern is the major geomorphic unit in western China.According to the geometric,dy-namic features of tectonic evolution of basins,the Cenozoic sedimentary basins in western China fall into four tectonic catego-ries:contractional basin,faulted basin,strike-slip pull-apart basin and remnant sea-foreland basin.These closed geomorphic basins in western China were surrounded by orogenic belts,which are divided by active compressive faults (thrust fault and strike-slip fault).Both the Indian-Eurasian plate collision and the intracontinental subduction play significant role in the forma-tion and evolution of sedimentary basins in western China.There is a close relationship among the tectonic lithofacies paleogeo-graphic evolution of sedimentary basins,plate movement and tectonic uplift.
