“…Furthermore, the process accommodated substantial clockwise rotation, e.g., the Chuxiong Basin with a rotation of 408-308 and the Xichang Basin with a rotation of 108-58, as indicated by Late Cretaceous to Tertiary palaeomagnetic data (Sato et al, 2001). Note that the NE-SW-oriented deformation is recognized across the eastern margin of the Tibetan Plateau and the upper Yangtze Block, e.g., Songpan-Ganze, the Sichuan Basin and the Badong Basin (Li et al, 2012a(Li et al, , 2012b(Li et al, , 2012cLiu et al, 2012;Wilson et al, 2006). Thus, we suggest that the Late Palaeogene (40-20 Ma) represents the D 3 deformation of the Daloushan, related to NE-SW-oriented shortening (D 3 , Fig.…”

“…Thus, we consider $80 Ma to be the time of the main phase deformation of the Daloushan (D 2 ). Such south-north-oriented deformations were recognized across the Yangtze Block, e.g., the southeastern Sichuan, the Yuanma and Badong basins (Li et al, 2012a(Li et al, , 2012b(Li et al, , 2012cLiu et al, 2012), showing a close correlation with the Xuefeng orogen.…”

“…Mesozoic angular unconformities (e.g., J 2 / K 1 ) become younger, fewer and weaker from the eastern side of the Xuefeng Orogen to the Daloushan, where a paraconformity is visible (BGMRSP, 1991). In particular, significant uplift and erosion has occurred since the Late Paleogene Li et al, 2012aLi et al, , 2012bLi et al, , 2012c, resulting in a restricted occurrence of Cenozoic rocks in the upper Yangtze Block. The Lower Cenozoic rocks show similar fluvial-lacustrine facies across the southern Sichuan basin and its periphery.…”

“…west-to NW-vergent thrusts and folds in the eastern Daloushan; a northwestward thrusting with shortening of $80-100 km that predominantly occurred in the Late Jurassic-Early Cretaceous, related to the Xuefeng Orogeny (Li et al, 2012a(Li et al, , 2012b(Li et al, , 2012cMei et al, 2010;Yan et al, 2003); a moderate-to-high angle unconformity between the K 2 / K 1 in the Yuanma Basin, located southeast away from the Daloushan (Li et al, 2012a(Li et al, , 2012b(Li et al, , 2012c); a widespread para-unconformity between the K 2 /K 1 across the southern Sichuan Basin; a pre-main phase folding affecting Early Cretaceous rocks also recognized in other areas of the Yangtze Block, e.g., the Yuanma Basin (Li et al, 2012a(Li et al, , 2012b(Li et al, , 2012c and the South China Block .…”

“…It indicates that deformation and exhumation occurred during the post-Late Palaeogene to Neogene (D 3 ). Li et al (2012aLi et al ( , 2012bLi et al ( , 2012c and Deng et al (2013) argued that major regional erosion across the Sichuan Basin started not earlier than 40-20 Ma, roughly later than the major plate reorganization of the Indo-Eurasia blocks (Najman et al, 2010). The latter resulted in largescale Tibetan crustal mass movement eastward, and development of numerous lithospheric-scale strike-slip faults and shortening, etc.…”

We applied the geomorphic indices (hypsometry and stream length gradient) to evaluate the differential uplift of the central and southern Longmenshan, a mountain range characterized by rapid erosion, strong tectonic uplift, and devastating seismic hazards. The results of the geomorphic analysis indicate that the Beichuan-Yingxiu fault and the Shuangshi-Dachuan fault act as major tectonic boundaries separating areas experiencing rapid uplift from slow uplift. The results of the geomorphic analysis also suggest that the Beichuan-Yingxiu fault is the most active fault with the largest relative uplift rates compared to the rest of the faults in the Longmenshan fault system. We compared reflected relative uplift rates based on the hypsometry and stream length gradient indices with geological/geodetic absolute rates. Along-strike and across-strike variations in the hypsometry and stream length gradient correlate with the spatial patterns derived from the apatite fission track exhumation rates, the leveling-derived uplift rate, and coseismic vertical displacements during the 2008 Wenchuan earthquake. These data defined multiple fault relationships in a complex thrust zone and provided geomorphic evidence to evaluate the potential seismic hazards of the southern Longmenshan range.GAO ET AL.

Sichuan Basin and beyond: Eastward foreland growth of the Tibetan Plateau from an integration of Late Cretaceous‐Cenozoic fission track and (U‐Th)/He ages of the eastern Tibetan Plateau, Qinling, and Daba Shan

Combining 121 new fission track and (U‐Th)/He ages with published thermochronologic data, we investigate the Late Cretaceous‐Cenozoic exhumation/cooling history of the eastern Tibetan Plateau, Qinling, Daba Shan, and Sichuan Basin of east central China. The Qinling orogen shows terminal southwestward foreland growth in the northern Daba Shan thrust belt at 100–90 Ma and in the southern Daba Shan fold belt at 85–70 Ma. The eastern margin of Tibetan Plateau experienced major exhumation phases at 70–40 Ma (exhumation rate 0.05–0.08 mm/yr), 25–15 Ma (≤1 mm/yr in the Pengguan Massif; ~0.2 mm/yr in the imbricated western Sichuan Basin), and since ~11–10 Ma along the Longmen Shan (~0.80 mm/yr) and the interior of the eastern Tibetan Plateau (Dadu River gorge, Min Shan; ~0.50 mm/yr). The Sichuan Basin records two basin‐wide denudation phases, likely a result of the reorganization of the upper Yangtze River drainage system. The first phase commenced at ~45 Ma and probably ended before the Miocene; >1 km of rocks were eroded from the central and eastern Sichuan Basin. The second phase commenced at ~12 Ma and denudated the central Sichuan Basin, Longmen Shan, and southern Daba Shan; more than 2 km of rocks were eroded after the lower Yangtze River had cut through the Three Gorges and captured the Sichuan Basin drainage. In contrast to the East Qinling, which was weakly effected by late Cenozoic exhumation, the West Qinling and Daba Shan have experienced rapid exhumation/cooling since ~15–13 Ma, a result of growth of the Tibetan Plateau beyond the Sichuan Basin.
