“…The basement is overlain by a low-grade metamorphosed Upper Neoproterozoic (Sinian; ca. 800-570 Ma) succession of laminated carbonates, volcanics, shales, marls and tuffites, which are wellexposed around the Akaz Pass (Mattern and Schneider, 2000). The laminated carbonates (parallel-bedded limestone and Pan et al, 2004;Xiao et al, 2005) and (b) simplified geological map of the Western Kunlun orogenic belt, Xinjiang, northwestern China (after Dong et al, 2004;Pan et al, 2004;Huang, 2014).…”

“…Therefore, the Sinian succession was interpreted as a rift sequence formed during the fragmentation of a shallow marine platform (Mattern et al, 1996;Pan, 1996). With the development of the Sinian rifting, ocean spreading might have taken place during the later Sinian to Early Paleozoic, which resulted in the formation of the Proto-Tethys Ocean whose remnants are found at the Oytag-Kudi suture (Pan, 1996;Mattern and Schneider, 2000). South-dipping subduction of the Proto-Tethyan oceanic crust during the Early Paleozoic (Late Cambrian to earliest Ordovician) may have generated an early Paleozoic granitoid belt that is preserved in the South Kunlun terrane close to the Oytag-Kudi suture (Xiao et al, , 2005Jiang et al, 2002Jiang et al, , 2013.…”

“…This subduction may have led to accretion of the arc onto the North Kunlun terrane, creating an active continental margin with north-dipping subduction underneath . It has been suggested that the collision between the North Kunlun and South Kunlun terranes might have occurred in the Silurian (Pan, 1996;Mattern and Schneider, 2000;Jiang et al, 2013), resulting in the closure of the Proto-Tethyan ocean (Mattern et al, 1996;Pan, 1996).…”

“…1a), represents a key tectonic junction between the Pan-Asia and the Tethyan tectonic domains. Its tectonic evolution was closely related to the subduction of the Proto-and Paleo-Tethys and the collision of the Early Paleozoic to Early Mesozoic terranes (Mattern and Schneider, 2000;Xiao et al, 2002Xiao et al, , 2003Jiang et al, 2013), and Cenozoic deformation by the far-field effects of the India-Asia collision (Matte et al, …”

Kinematics of Active Deformation Across the Western Kunlun Mountain Range (Xinjiang, China) and Potential Seismic Hazards Within the Southern Tarim Basin

et al. 2017

The Western Kunlun mountain range is a slowly converging intracontinental orogen where deformation rates are too low to be properly quantified from geodetic techniques. This region has recorded little seismicity, but the recent July 2015 (Mw 6.4) Pishan earthquake shows that this mountain range remains seismic. To quantify the rate of active deformation and the potential for major earthquakes in this region, we combine a structural and quantitative morphological analysis of the Yecheng–Pishan fold, along the topographic mountain front in the epicentral area. Using a seismic profile, we derive a structural cross section in which we identify the fault that broke during the Pishan earthquake, an 8–12 km deep blind ramp beneath the Yecheng–Pishan fold. Combining satellite images and DEMs, we achieve a detailed morphological analysis of the Yecheng–Pishan fold, where we find nine levels of incised fluvial terraces and alluvial fans. From their incision pattern and using age constraints retrieved on some of these terraces from field sampling, we quantify the slip rate on the underlying blind ramp to 0.5 to 2.5 mm/yr, with a most probable long‐term value of 2 to 2.5 mm/yr. The evolution of the Yecheng–Pishan fold is proposed by combining all structural, morphological, and chronological observations. Finally, we compare the seismotectonic context of the Western Kunlun to what has been proposed for the Himalayas of Central Nepal. This allows for discussing the possibility of M ≥ 8 earthquakes if the whole decollement across the southern Tarim Basin is seismically locked and ruptures in one single event.

Structural analysis of ductile shear zones in the North Qinling Orogen and its implications for the evolution of the Proto‐Tethys Ocean

The ductile shear zones in the North Qinling Orogen, such as the Luonan‐Luanchuan, Guanpo‐Qiaoduan, Zhuyangguan‐Xiaguan, and Shangdan shear zones, play an important role in the preclosure and postclosure evolution of the Proto‐Tethys Ocean. On the basis of detailed macrostructural/microstructural analysis and quartz C‐axis electron backscattered diffraction fabric analysis, the sense and formation environment of the 4 shear zones have been obtained. The Luonan‐Luanchuan and Guanpo‐Qiaoduan shear zones mainly present as dextral and sinistral shearing under low temperature, respectively. The Zhuyangguan‐Xiaguan shear zone mainly presents as dextral shearing under medium temperature. The Shangdan shear zone underwent an early dextral shearing under medium temperature and a late sinistral shearing under low temperature. The Qinling Group and the Taibai region were intensively affected by the late sinistral shearing of the Shangdan shear zone. According to published metamorphic ages, the 4 shear zones should have been formed during the collision between the North China Block and the South China Block. Due to the opening of the Mianlue and the Paleo‐Tethys oceans since ~380 Ma, the North China Block and the South China Block departed from northern Gondwanaland and drifted northward along transform faults, which led to the arrangement between the North China Block and the South China Block that transited from an east–west direction to a north–south direction. Since ~320 Ma, the scissors‐type closure between the North China Block and the South Qinling Terrane led to the westward extrusion of the North Qinling Orogen, and the dextral shearing of the Luonan‐Luanchuan and the Zhuyangguan‐Xiaguan shear zones and the sinistral shearing of the Guanpo‐Qiaoduan and the Shangdan shear zones.
