Brittle modification of Triassic architecture in eastern Tibet: implications for the construction of the Cenozoic plateau

Late Triassic high-Mg andesite/dacite suites from northern Hohxil, North Tibet: Geochronology, geochemical characteristics, petrogenetic processes and tectonic implications

“…Similar Triassic flysch complexes also occur to the north of the Anyimaqen-Kunlun-Muztagh suture and to the south of the Jinshajiang suture (Xiao et al, 2002a,b;Yin and Harrison, 2000). The Songpan-Ganzi flysch complex was intensely deformed by folding and thrusting during the Late Triassic and Early-Middle Jurassic (205-165 Ma) (Burchfiel et al, 1995;Huang et al, 2003;Wilson et al, 2006).…”

Structural geometry and kinematic processes at the intracontinental Daloushan mountain chain: Implications for tectonic transfer in the Yangtze Block interior

“…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.…”

“…The latter is attributed to an eastward extrusion of crustal material from the Tibetan Plateau (Royden et al, 2008;Wilson et al, 2006).Within the SCB, the Sichuan Basin is separated from a 1300-kmwide Mesozoic intracontinental orogenic belt by the Qiyueshan-Daloushan Mountains. These mountains underwent a complicated tectono-magmatic evolution during the Late Mesozoic, referred to as the Yanshanian Intracontinental Orogeny (Hsu et al, 1990).…”

GPS Strain Rate and Seismic Activity Before the Ludian Earthquake (Ms 6.5), Northeast Yunnan, China: New Implications for Eastward Chuan-Dian Block Extrusion

“…The CDB is defined by the XianshuiheXiaojiang fault in the northeast and the Red River fault in the southwest (Huchon et al 1994;Wang et al 1998;Su et al 2012). The northern half of the CDB contains a conjugate set of strike-slip faults, which together accommodate this fragment's lateral extrusion from the N-S compression region to the west (directly north of the corner of the India indenter), as indicated by left-and right-lateral strike-slip faults (Wilson et al 2006;Su et al 2012). To the south, however, almost all of the strike-slip faults are arranged with a N-S striking.…”
