Geodesy and Geodynamics, 2019 The average density of 3300 kg m−3 is often attributed for the asthenosphere. In this study, we inspect this value by estimating the average value of the (upper) asthenosphere based on applying the gravimetric forward modelling of major known ...

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

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

Геодинамика и тектонофизика, 2017 A comprehensive model for deep dynamics in Asia has been developed from the data on the evolution of melting anomalies in the context of lithospheric plate motions, interactions, orogeny, and rifting.

The lithosphere-asthenosphere: Italy and surroundings
Episodes, 2003 Abstract The velocity-depth distribution of the lithosphere-asthenosphere in the Italian region and surroundings is imaged, with a lateral resolution of about 100 km, by surface wave velocity tomography and non-linear inversion. Maps of the Moho depth, of the thickness of the lithosphere and of the shear-wave velocities, down to depths of 200 km and ...

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,

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.

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin
Geological Journal, EarlyView.Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.

Geochemistry, Geophysics, GeosystemsSubduction zones are fundamental features of Earth's mantle convection and plate tectonics, but mantle flow and pressure around slabs are poorly understood because of the lack of direct observational constraints on subsurface flow.
