Abstract:Based on field observation, Landset image, well and seismic data, two regional cross sections have been constructed in Quele area, Kuqa depression. The main salt structural styles in study area are salt diapirs, salt welds, salt withdrawal minibasins, large-scale salt nappe, allochthonus salt sheet, salt pillow, salt anticlines, and detachment folds. The main difference between eastern and western segments is that salt withdrawal minibasins, salt anticlines and detachment folds only developed in the eastern segment. Salt structures formed in three growth stages from Oligocene to present: (1) during Oligocene to early Miocene, salt withdrawal minibasin and passive diapirs formed; (2) from late Miocene to early Pliocene, early folding developed under weak regional compression, meanwhile, Quele salt dome continue to growth passively and the northern diapir ceased at the end of Miocene; and (3) since late Pliocene to present, large-scale minibasins, allochthonus salt sheet, salt pillow, salt anticlines, and detachment folds formed. This is the major period of folding, thrusting, and squeezing diapirs in Quele area. Deformation difference between eastern and western segments formed mainly during the third stage. Karayulgun dextral strike-slip fault, which is a thin-skinned structure, adjusted the deformation difference located at frontal range of Quele area. The major controlling factors of salt structures include the distribution of salt, regional tectonic stress and strength, strength of overburden and differential loading (Sedimentary loading and local structural loading).
