“…The Late Permian Emeishan mantle plume on the western margin of the South China Block is considered to have caused the inferred rifting (e.g., Chung and Jahn, 1995;Song et al, 2004). In the second model, the Songpan-Ganzi basin is interpreted as a back-arc basin between the Kunlun arc to the north and the outboard Yidun arc to the south (e.g., Burchfiel et al, 1995;Pullen et al, 2008;Şengör et al, 1988;Watson et al, 1987) (Fig. 1).…”

“…The tectonic setting of these sedimentary strata has long been disputed. Based on tectonic and sedimentary analyses, the strata were considered to have formed in a variety of tectonic settings such as an intracontinental rift (e.g., Song et al, 2004), a back-arc basin (e.g., Burchfiel et al, 1995;Pullen et al, 2008;Şengör et al, 1988;Watson et al, 1987), a foreland basin (Yuan et al, 2010), and a remnant oceanic basin (e.g., Nie et al, 1994;Weislogel, 2008;Weislogel et al, 2006;Yin and Harrison, 2000;Zhou and Graham, 1996). So far, the majority of HSGB studies have been conducted in the east, where interactions with surrounding blocks (e.g., the South China, Kunlun-Qaidam, North China, South Qinling, Qilian, Yidun, and Qiangtang Blocks; Fig.…”

“…Gabbros form the highest peaks of Bogdo Shan [Chen et al, 1985] (Plate 1). These rocks represent evidence of an island arc, which formed an active margin south of Dzungaria in the late Carboniferous [e.g., Carroll et al, 1990;Windley et al, 1990]. In the central Tien Shan, between Urumqi and Korla, Windley et al [1990] distinguish two sutures of different ages and opposite vergence (late Devonian and north dipping in the south; late Carboniferous and south dipping in the north) (Plate 1).…”

“…In the central Tien Shan, between Urumqi and Korla, Windley et al [1990] distinguish two sutures of different ages and opposite vergence (late Devonian and north dipping in the south; late Carboniferous and south dipping in the north) (Plate 1). Steeply dipping mylonites and sheared melange imply postcollisional strike-slip movement along the northern suture west of Turfan [Windley et al, 1990;M. Mattauer, personal communication, 1987].…”

We have studied geometries and rates of late Cenozoic thrust faulting and folding along the northern piedmont of the Tien Shan mountain belt, West of Urumqi, where the M=8.3 Manas earthquake occurred on December 23, 1906. The northern range of the Tien Shan, rising above 5000 m, overthrusts a flexural foredeep, filled with up to II ,000 m of sediment, of the Dzungarian basement. Our fieldwork reveals that the active thrust reaches the surface 30 km north of the range front, within a 200-km-long zone of NeogeneQuaternary anticlines. Fault scarps are clearest across inset terraces within narrow valleys incised through the anticlines by large rivers flowing down from the range. In all the valleys, the scarps offset vertically the highest terrace surface by the same amount (10.2±0.7 m). Inferring an early Holocene age (10±2 kyr) for this terrace, which is continuous with the largest recent fans of the piedmont, yields a rate of vertical throw of 1.0±0.3mm/yr on the main active thrust at the surface. A quantitative morphological analysis of the degradation of terrace edf,es that are offset by the thrust corroborates such a rate and yields a mass diffusivity of 5.5±2.5 m /kyr. A rather fresh surface scarp, 0.8±0.15 m high, that is unlikely to result from shallow earthquakes with 6 < M < 7 in the last 230 years, is visible at the extremities of the main fold zone. We associate this scarp with the 1906 Manas earthquake and infer that a structure comprising a deep basement ramp under the range, gently dipping flats in the foreland, and shallow ramps responsible for the formation of the active, fault propagation anticlines could have been activated by that earthquake. If so, the return period of a 1906 type event would be 850 ± 380 years. The small size of the scarp for an earthquake of this magnitude suggests that a large fraction of the slip at depth ( ""2/3) is taken up by incremental folding near the surface. Comparable earthquakes might activate flat detachments and ramp anticlines at a distance from the front of other rising Quaternary ranges such as the San Gabriel mountains in California or the Mont Blanc-Aar massifs in the Alps. We _,:stimate the finite Cenozoic shortening of the folded Dzungarian sediments to be of the order of 30 km and the Cenozoic shortening rate to have been 3 ± 1.5 mrnlyr. Assuming comparable shortening along the Tarim piedmont and minor additional active thrusting within the mountain belt, we infer the rate of shortening across the Tien Shan to be at least 6±3 mm/yr at the longitude of Manas (""85.5°E). A total shortening of 125±30 km is estimated from crustal thickening, assuming local Airy isostatic equilibrium. Under the same assumption, serial N-S sections imply that Cenozoic shortening across the belt increases westwards to 203±50 km at the longitude of Kashgar ( ""76°E), as reflected by the westward increase of the width of the belt. This strain gradient implies a clockwise rotation of Tarim relative to Dzungaria and Kazakhstan of 7 ± 2.5 • around a pole located near the eastern extr...

“…Previous studies have shown that the closure and collision of the Okhotsk Sea to the north and the Pacific Plate subduction beneath the Asian continent to the east are the major tectonic events resulting in the formation and evolution of the SLB (Watson et al, 1987;Feng et al, 2010;Yang, 2013). The evolution of the SLB includes a synrift stage from the Late Jurassic to Early Cretaceous, followed by a depression in the Late Cretaceous, and a structural inversion in the Cenozoic (Feng et al, 2010).…”
