Rock and isotopic age of the collision structures in Pamir region have recorded the movement of Indian plate toward Asian plate

which has experienced subduction and consumption of Neo-Thetys (113±1.5Ma-71.1±1.4Ma)

collision of Indian and Asian plates(36.95±1.2Ma) and continuous squeezing after collision (6.69-6.80Ma). The Jurassic-Cretaceous in the southwestern Tarim Basin/Paleogene foreland basin

located in front of the Pamir thrust zone

have been reformed by the collision of Indian and Asian plates

and only the Maigaiti slope zone and Tazhong-Bachu frontal uplift zone have survived. The subsidence center of the Miocene-Quaternary foreland basin has migrated northward to Yecheng-Kashi where 5000～6000m of coarse clastic sediments have been accumulated as a result of rapid subsidence. Kuqa Meso-Cenozoic foreland basin on the southern side of Tianshan orogenic belt has relatively complete structures with smaller reformation than that in southwestern Tarim

hence the Yiqikelike-Kelasu Jurassic-Cretaceous/Paleogene foredeep subsiding zone

Qiulitage-Yaken slope zone and Yaha-Tabei fontal uplift zone have been preserved. Most of the Triassic-Jurassic/Early Cretaceous strata have been transformed into thrust fault and fault-bended and fault-extended fold belts

as well as the aggrading deformable zone of detachment faults and decollement folds in Qiulitage-Yaken slope zone during the Miocene collision. Later

they have been preserved by the superimposition and overlap of the southward migrating Baicheng-Yangxia Pliocene-Quaternary sag

thus they have been provided with the conditions for the formation of large gas accumulations. During the squeezing and strike-slip displacement stages after the Miocene collision of Indian and Asian plates

deep in-situ deformable bodies or anticlines

such as Yingjisha and Mingluyao etc. have been formed in Kashi depression

and in-situ folded deformable structures of collision stage (stage Ⅱ) might also exist in deep Cretaceous-Lower Tertiary in Atushi anticline

Kelasu anticline

Talanghe and Alabulake in west Tianshan mountain front. These structures should be the main exploration targets in Tarim basin.
