ABSTRACT This paper deals with the Tertiary tectonic and sedimentary evolution of western Tarim basin based on an integrated stratigraphic, sedimentary, structural, analyses. Basin is divided into three stages: Paleogene, Miocene, Pliocene. The was easternmost part Tethyan realm from Late Cretaceous to marine sedimentation continued Early Miocene. Miocene development chiefly governed by West Kunlun right‐slip faulting simultaneous northward thrusting Pamir salient Tianshuihai terrane. Yecheng subbasin developed as a pull‐apart owing synchronous activity Shache‐Yangdaman faults. Hotan foreland formed in response displacement terrane, another might have front advancing Basinward became predominant orogenic belts adjacent North‐directed uplift Tiklik thrust terrane fragmented preexisting basin, collision southern Tian Shan deformational fronts caused complete destruction basin. Eastward Qimugen fold‐thrust system led flexural subsidence Kashi controlled eastern well. A scenario proposed illustrate complicated interplay its peripheral orogens Tertiary.
