Abstract: The formation and evolution of Mesozoic and Cenozoic Kuche-Baicheng and Kashi-Yecheng foreland basins in Tarim are related to the close of Tethys and long-range effects produced by the subduction and collision of Indian plate to Eurasian plate. It is mainly showed that the basement of Tarim Basin subducted intracontinentally to peripheral West Kunlun and Tianshan orogenic belts to form crust-stacked wedges, the thrust sheets of orogenic belts napped basinward in a large scale, and the basement of the basin flexurally subsided to form compressional foredeeps, By a large amount of fabric analyses and three-dimensional finite strain measures, the basinward napping distance of orogenic belts, the progressive metamorphic patterns and compressed volume of foreland basins and the trapping types and hydrocarbon domains formed are calculated.
