Abstract The Cenozoic India-Asia collision reactivated several ancient thrust belts in the interior of the Asian continent, including the West and East Kunlun ranges in central Tibet, and the Tian Shan and Qilian Shan further north. Both basin sedimentary records and thermochronological data show that the uplift of the South Tian Shan and Qilian Shan at the north occurred earlier than that of the West and East Kunlun ranges at the south. Diachronous continental deformation and initiation of upli...

There are usually abrupt changes in lithospheric thickness at the boundaries between ancient cratons and adjacent young mobile belts. Lateral variations in temperature and density between the two can trigger small-scale mantle convection (edge-driven convection, EDC). Here, we use two-dimensional thermal-mechanical simulations to explore the EDC caused by the lithospheric step between a craton and a mobile belt, and its role in the thinning of the craton lithosphere. The results show that the im...

Abstract The northeastern margin of Tibet is the youngest risen part and key area for understanding the growth mechanism of the Tibetan Plateau. New broadband magnetotelluric (MT) data are conducted at the conjunction of the Longmenshan and West Qinling orogenic belts in NE Tibet. The preferred resistivity model obtained using 3-D inversion method shows a dramatic resistivity contrast from the Sichuan Basin (SB) to the West Qinling Orogenic Belt (WQOB). Beneath the SB and Longmenshan Orogenic Be...

Abstract Mid-crustal melting is widely documented under orogenic plateaus. However, the mechanism for its generation and its role in the evolution of orogenic plateaus remain poorly understood. Here we investigate the physical controls and consequences of crustal melting in plateau evolution using 3-D thermo-mechanical modeling method. Our simulations demonstrate that the convergence causes orogenic crust to have more upper crustal compositions and more radiogenic elements. The persistent radioa...

The formation of the Tibetan plateau during the India-Asia collision remains an outstanding issue. Proposed models mostly focus on the different styles of Tibetan crustal deformation, yet these do not readily explain the observed variation of deformation and deep structures along the collisional zone. Here we use three-dimensional numerical models to evaluate the effects of crustal rheology on the formation of the Himalayan-Tibetan orogenic system. During convergence, a weaker Asian crust allows...

Abstract We investigate the kinematics of continent breakup and seafloor spreading in response to the upwelling divergent mantle flow using the optimal nearly-analytical discrete method. Modeling results show that a larger upwelling rate ( V z ) in the upwelling divergent flow system favors the earlier development of continent breakup and seafloor spreading and the formation of narrow continental rifted margins and mantle exhumation; while a larger half divergent rate ( V x ) favors the diffusiv...

The Qinling-Dabie orogen is an important tectonic belt that trends east-west and divides continental China into northern and southern parts. Due to its strong deformation, complicated structure, multiphase structural superposition and the massive exposed high and ultrahigh metamorphic rocks, its tectonic formation and geodynamical evolution are hot research topics worldwide. Previous studies mainly focused on the regional geological or geochemical aspects, whereas the geophysical constraints are...
