塔里木中新生代库车一拜城、喀什一叶城前陆盆地的形成与演化是与特提斯洋关闭、印度板块对欧亚板块的俯冲、碰撞所产生的远程效应相联系的，主要是：塔里木盆地基底向周缘的西昆仑、天山造山带陆内俯冲形成地壳叠加楔；造山带逆冲岩席向盆地的大规模推覆；盆地基底挠曲沉降形成挤榨前渊。通过大量的组构分析和三维有限应变测量，计算了造山带向盆地的推覆距离、前陆盆地的递进变形方式和压缩量以及所形成的圈闭类型和油气领域。
The formation and evolution of the Mesozoic-Cenozoic kuche-Baicheng, Kashi-Shiye foreland basin are related to the teleconnection of the Tethyan ocean and the subduction and collision of the Indian plate with the Eurasian plate, mainly : The basement of the Tarim Basin formed a superimposed wedge of intracontinental subduction in the western Kunlun and Tianshan orogenic belts along the periphery of the Tarim Basin. Large-scale thrusting of thrust basins in the orogenic belts to the basin resulted in the formation of a squeezed front in the basin. Through extensive structural analysis and three-dimensional finite strain measurements, the range of uplift of the orogenic belt to the basin, the progressive deformation mode and amount of compression in the foreland basin, and the formation of traps and hydrocarbon fields have been calculated.
