Viscoelastic relaxation of the upper mantle and afterslip following the 2014 MW8.1 Iquique earthquake

Earthquake Research Advances, 2021
An improved understanding of postseismic crustal deformation following large subduction earthquakes may help to better understand the rheological properties of upper mantle and the slip behavior of subduction interface.

Microplate Tectonics Through Earth History and Across Solid Multispheres

Geological Society of China Bulletin, EarlyView.
The evolution of tectonic microplates throughout Earth´s history as well as the transitions between microplates across different solid spheres offers a novel approach to expanding the traditional plate tectonics theory. ABSTRACT The evolution of tectonic microplates throughout Earth's history as well as the transitions between microplates across ...

PLUTONIC STRUCTURE OF THE DEEP-SEA BASINS IN THE SEA OF OKHOTSK REGION

Геодинамика и тектонофизика, 2018
The original continental crust of the deep-sea basins in the Sea of Okhotsk region was considerably reworked by tectonic and magmatic processes, whereby it has become substantially denser while less thick.

Continental Thermal Blanketing Explains the Compositional Dichotomy of the Diffuse Basaltic Province Across Central‐Eastern Asia

Geophysical Research Letters, 2023
A diffuse magmatic province covering central‐eastern Asia continent displays a compositional transition at 120–100 Ma and probably reflects melting initiation in isotopically enriched lithospheric mantle, followed by melting of the asthenosphere. However,

Upper mantle anisotropy from shear wave splitting of teleseismic earthquakes in the Kumaun-Garhwal and adjoining area of NW Himalaya

Journal of Asian Earth Sciences: X, 2021
Teleseismic earthquakes data recorded by 8 broadband digital seismic stations deployed in the Kumaun-Garhwal and adjoining area of NW Himalaya are analyzed to investigate the seismic anisotropy in the upper mantle. Shear-wave splitting parameters (ɸ and ∂

Weak asthenosphere of Sumatran backarc revealed by long postseismic geodetic records

Communications Earth & Environment
The viscosity of Earth’s asthenosphere regulates plate motion and surface deformation. Assessing asthenosphere rheology in subduction-zone backarcs is as crucial as in forearc and arc regions for understanding subduction dynamics.

Application of a Premelting Model to the Lithosphere‐Asthenosphere Boundary

Geochemistry, Geophysics, Geosystems, 2020
A seismic discontinuity known as the G‐discontinuity, which has been prevailingly detected in the oceanic mantle, is considered to provide evidence of a sharp lithosphere‐asthenosphere boundary (LAB). We investigate whether this sharp LAB is explained by

The Lithosphere‐Asthenosphere System Beneath the North Atlantic and Surroundings: Results From Multi‐Observable Probabilistic Inversions

Geochemistry, Geophysics, Geosystems
The North Atlantic region is a complex geodynamic setting that comprises multiple continental blocks, sedimentary basins, mid‐ocean ridge systems and prominent hotspots.

COMPOSITIONAL AND THERMAL DIFFERENCES BETWEEN LITHOSPHERIC AND ASTHENOSPHERIC MANTLE AND THEIR INFLUENCE ON CONTINENTAL DELAMINATION

Геодинамика и тектонофизика, 2015
The lower part of lithosphere in collisional orogens may delaminate due to density inversion between the asthenosphere and the cold thickened lithospheric mantle. Generally, standard delamination models have neglected density changes within the crust and
