“…Both Global Positioning System measurements and studies of late Quaternary faulting are consistent with a slip rate of 10 mm/yr along the central ATF, and a systematic decrease in that rate toward the eastern end of the fault Zheng et al, 2013). A ''two-stage'' model was proposed by Yue and Liou (1999): the first stage of movement of the ATF system may have begun around Oligocene time; the second stage of displacement of this part of the ATF was partly responsible for crustal thickening and rapid uplift along the northeastern margin of the Tibetan Plateau at 16-13 Ma. Yin et al (2002) proposed a ''continuum'' model for displacement of the ATF; its continuous motion eventually closed the outlets of westward flowing drainage into the Qaidam Basin, and caused large amounts of sediment to be trapped in the basin during the Oligocene-Miocene.…”

“…Our results show that the Eastern Tianshan Mountains undertook slow uplifting during 65-35 Ma (Figures 12 and 13), which may mean that the effect of the IndoEurasian collision may have touched the Eastern Tianshan Mountains at that time, but it was very weak. Although without more data, we incline that the initial slow uplifting of the Eastern Tianshan Mountains during the Early Cenozoic did not result from the Indo-Eurasian and it not only was one important period for tectonic transformation from early large scale strike-slipping to late crust thickening [41,42] but also one important period for the Plateau to expand to the north [43][44][45][46] . This study showed the strong uplifting of Eastern Tianshan Mountains also occurred in about 24 Ma, so we suggest that the uplifting of the whole Tianshan Mountains during Oligocene-Miocene has a close relation to the coeval tectonic events of the Qinghai-Tibet Plateau, which was the response of the northward expanding of the Plateau.…”

The Tianshan Mountains have undergone its initial orogeny, extension adjusting and re-orogeny since the Late Paleozoic. The re-orogeny and uplifting process of the orogeny in the Mesozoic and Cenozoic are two of most important events in the geological evolution of Euro-Asian continent, which resulted in the formation of the present range-and-basin pattern in topography of the Tianshan Mountains and its adjacent areas. Thermochronology results by the method of fission-track dating of apatite suggest three obvious uplifting stages of the Bogad Mountain Chain re-orogeny during the Cenozoic, i.e. 5.6-19 Ma, 20-30 Ma, and 42-47 Ma. The strongest uplifting stage of the mountain is the second one at 20 -30 Ma, when the mountain uplifted as a whole, and the beginning of re-orogeny was no less than 65 Ma. Furthermore, our studies also show that the uplifting types of the mountain are variable in the different time periods, including uplifting of mountain as a whole and differential uplifting. The apparently diversified uplifting processes of the mountain chain are characterized by the migration (or transformation) of the uplifting direction of the mountain from west to east and from north to south, and the main process of mountain extending is from north to south.

“…However, this requires an accelerated slip rate between 25 and 17 Ma of 300 km offset (c. 40 mm a À1 ). Therefore a two-stage evolution in fault kinematics has been suggested with fast slip and extrusion during the Late Oligocene-Early Miocene changing to slow slip and crustal thickening up to the present (Yue & Liou 1999;Yue et al 2003;Ritts et al 2008). …”

Crustal shortening and thickening to c. 70-85 km in the Tibetan Plateau occurred both before and mainly after the c. 50 Ma India-Asia collision. Potassic-ultrapotassic shoshonitic and adakitic lavas erupted across the Qiangtang (c. 50-29 Ma) and Lhasa blocks (c. 30-10 Ma) indicate a hot mantle, thick crust and eclogitic root during that period. The progressive northward underthrusting of cold, Indian mantle lithosphere since collision shut off the source in the Lhasa block at c. 10 Ma. Late Miocene-Pleistocene shoshonitic volcanic rocks in northern Tibet require hot mantle. We review the major tectonic processes proposed for Tibet including 'rigid-block', continuum and crustal flow as well as the geological history of the major strikeslip faults. We examine controversies concerning the cumulative geological offsets and the discrepancies between geological, Quaternary and geodetic slip rates. Low present-day slip rates measured from global positioning system and InSAR along the Karakoram and Altyn Tagh Faults in addition to slow long-term geological rates can only account for limited eastward extrusion of Tibet since Mid-Miocene time. We conclude that despite being prominent geomorphological features sometimes with wide mylonite zones, the faults cut earlier formed metamorphic and igneous rocks and show limited offsets. Concentrated strain at the surface is dissipated deeper into wide ductile shear zones.
