DOI: 10.1007/s11430-019-9380-2
Abstract: The Longmenshan fault, which defines the eastern edge of the Tibetan Plateau, is one of the steepest margins of the plateau with a sharp elevation drop of about 4 km over a distance less than… read more here.

A mantle convection perspective on global tectonics

DOI: 10.1016/j.earscirev.2016.11.006
Abstract: The concept of interplay between mantle convection and tectonics goes back to about a century ago, with the proposal that convection currents in the Earth's mantle drive continental drift and deformation (Holmes, 1931). Since this… read more here.

DOI: 10.1016/j.epsl.2020.116439
Abstract: Abstract Mantle plumes provide valuable information about whole-mantle convection: they originate at the core-mantle boundary, cross Earth's mantle and interact with the lithosphere. For instance, it has been proposed that the mobility/stability of plumes depends… read more here.

DOI: 10.1016/j.gca.2019.03.039
Abstract: Abstract The lithospheric mantle beneath Archean cratons is conspicuously refractory and thick compared to younger continental lithosphere ( Jordan, 1988 , Boyd, 1989 ; Lee and Chin, 2014), but how such thick lithospheres formed is… read more here.

DOI: 10.1016/j.lithos.2021.106305
Abstract: Abstract Submicroscopic to micro-diamonds, silicates, wustite, platinum group minerals (PGM), sulfides and ultra-high pressure (UHP) mineral inclusions have been recovered from podiform and banded chromitites of the Bulqiza ophiolite in Albania. The alignment of acicular… read more here.

The Robustness of Pressure‐Driven Asthenospheric Flow in Mantle Convection Models With Plate‐Like Behavior
Sign Up to like & getrecommendations! Published in 2020 at "Geophysical Research Letters"
DOI: 10.1029/2020gl089556
Abstract: Recent seismic observations challenge the conventional view that tectonic plates are driven by slab pull and ridge push forces. The observations indicate that the asthenosphere flows faster and in a different direction than the plate… read more here.

DOI: 10.1093/gji/ggab197
Abstract: In order to generate plate tectonics, the near surface layer should not be too strong, but the causes for not-so-strong near surface layer remains unclear. We conduct mantle convection modelling in the spherical geometry to… read more here.

DOI: 10.1126/science.363.6428.703-o
Abstract: Geophysics The boundaries between rocks with different physical properties in Earth's interior come from either a change in crystal structure or a change in chemical composition. Wu et al. examined the roughness of the boundary… read more here.

DOI: 10.1134/s0016852118050072
Abstract: The study concerns two deep sources of tectonic processes in Late Mesozoic and Cenozoic which influence is transferred and enforced on the spheroid surface – Earth crust. The first source is mantle convection. Its upgoing… read more here.
