TLDR
The Longmen Shan region can be divided into two major tectonic elements: (1) an autochthon/parautochthons which underlies the easternmost part of the Tibetan Plateau, the Sichuan Basin, and the eastern SICHuan fold-and-thrust belt as discussed by the authors.Abstract:
The Longmen Shan region includes, from west to east, the northeastern part of the Tibetan Plateau, the Sichuan Basin, and the eastern part of the eastern Sichuan fold-and-thrust belt. In the northeast, it merges with the Micang Shan, a part of the Qinling Mountains. The Longmen Shan region can be divided into two major tectonic elements: (1) an autochthon/parautochthon, which underlies the easternmost part of the Tibetan Plateau, the Sichuan Basin, and the eastern Sichuan fold-and-thrust belt; and (2) a complex allochthon, which underlies the eastern part of the Tibetan Plateau. The allochthon was emplaced toward the southeast during Late Triassic time, and it and the western part of the autochthon/parautochthon were modified by Cenozoic deformation. The autochthon/parautochthon was formed from the western part of the Yangtze platform and consists of a Proterozoic basement covered by a thin, incomplete succession of Late Proterozoic to Middle Triassic shallow-marine and nonmarine sedimentary rocks interru...read more

Geologic Evolution of the Himalayan-Tibetan Orogen
An Yin,T. Mark Harrison +1 more
TL;DR: A review of the geologic history of the Himalayan-Tibetan orogen suggests that at least 1400 km of north-south shortening has been absorbed by the orogen since the onset of the Indo-Asian collision at about 70 Ma as discussed by the authors.

Topographic ooze: Building the eastern margin of Tibet by lower crustal flow
Marin K. Clark,Leigh H. Royden +1 more
TL;DR: In this article, the authors compare regional topographic gradients surrounding the Tibetan plateau to model results for flux of a Newtonian fluid through a lower crustal channel of uniform thickness.

Surface Deformation and Lower Crustal Flow in Eastern Tibet
Leigh H. Royden,B. Clark Burchfiel,Robert W. King,Erchie Wang,Zhiliang Chen,Feng Shen,Y. Liu +6 more
TL;DR: This model predicts east-west extension on the high plateau without convective removal of Tibetan lithosphere and without eastward movement of the crust east of the plateau.

TL;DR: In this article, the present-day tectonics in the Tibetan Plateau is best described as deformation of a continuous medium, at least when averaged over distances of.;100 km.
Journal ArticleDOI
The Geological Evolution of the Tibetan Plateau
TL;DR: Cessation of rapid Pacific trench migration coincided with a slowing of fragment extrusion beyond the plateau and probably contributed to the onset of rapid surface uplift and crustal thickening in eastern Tibet.

On the mechanics of the collision between India and Asia
TL;DR: The reproducible pattern of faulting obtained from plane-strain indentation experiments on unilaterally confined blocks of plasticine suggests that this extrusion process has occurred during most of the collision history as discussed by the authors.

The tectonic evolution of the Tibetan Plateau
TL;DR: In this paper, it was shown that the Lhasa terranes accreted to the Songban Ganzi Terrane along the Kunlun-Qinling Suture during the late Permian and the Qiangtang Terrane followed by a southward ophiolite obduction along the Zangbo Suture in the latest Cretaceous-earliest Palaeocene.

Extension during continental convergence, with application to the Tibetan Plateau
TL;DR: In this paper, an explanation in terms of the thermal evolution of thickened continental lithosphere is offered to explain the transition from north-south compression to east-west extension in the strain rate field of the Tibetan Plateau.

An indentation model for the North and South China collision and the development of the Tan‐Lu and Honam Fault Systems, eastern Asia
An Yin,Shangyou Nie +1 more
TL;DR: In this article, the authors proposed a boundary geometry model for the collision of the North China Block and the South China Block (SCB) that predicts the distribution and ages of metamorphism along the suture and the observed local but intense Triassic deformation.

Kinematic model of active deformation in central Asia
TL;DR: In this article, the velocity field of present-day deformation in Central Asia is modelled using a set of four rotating blocks (Siberia, Tarim, Tibet, India) on a spherical earth.
