Abstract

The Southern Tianshan thrust-fold systems are thin skin thrust structural belts formed after Miocene and Pliocene. Thrusting resulted in Palaozoic-Cenozoic clastic and carbonate rocks deforming in basin and margins regions. The kinematics characters of thrust front regions (Northern Bainkuluti and Kashi) were discussedThe Southern Tianshan thrust-fold systems were divided into six structural belts on plane and two tectonic layers in section. The blind thrust structural deltas were formed in thrust belts front.Thrusting made for Miocene strata deformation, uplift and denudation. There were two detachment surfaces. Thrusting on detachment surfaces gradually spreaded toward foreland and formed fault-related folds. That embranchment faults formed during structure activity made thrust belts more complication.The author indicated that thrust propagating of the Southern Tianshan thrust-fold systems were inverted sequence. The results were different from sequence of thrust-fold belts in Western Kunlun Mountain. It implicated that the Southern Tianshan thrust-fold systems were provided with unique kinematics characters. Using method of the balanced section, the structural crossing section was made and restored on the based of geology and geophysical data. Sequentially these were got that shorting percentage of the Southern Tianshan thrust-fold systems was 30%、that shorting amount was 50km and that shorting velocity was 9-10mm/a.
