Mantle Dynamics of the Long‐Lived Middle Yangtze Basaltic Field: Insight From a Combined Geochemical and Numerical Modeling Approach

open access: yesGeochemistry, Geophysics, Geosystems
Melting for the generation of intracontinental diffuse basaltic fields is generally ascribed to the effects from lithospheric dynamic processes, but how the asthenospheric dynamics influence the overlying lithosphere remains poorly known.

A multilayer model of time dependent deformation following an earthquake on a strike-slip fault [PDF]

open access: yes
A multilayer model of the Earth to calculate finite element of time dependent deformation and stress following an earthquake on a strike slip fault is discussed. The model involves shear properties of an elastic upper lithosphere, a standard viscoelastic

Delamination Magmatism in Eastern Anatolia: A Geochemical Perspective

open access: yesGeochemistry, Geophysics, Geosystems
The Sr‐Nd‐Hf‐Pb isotope geochemistry of the Late Miocene Tunceli Volcanics suggests that they are the products of mixed asthenospheric and lithospheric mantle melts.

Satellite magnetic modeling of north African hot spots [PDF]

open access: yes
The primary objectives of the MAGSAT mission was to measure the intensity and direction of magnetization of the Earth's crust. A significant effort was directed to the large crustal anomalies first delineated by the POGO mission.

Postseismic viscoelastic surface deformation and stress. Part 1: Theoretical considerations, displacement and strain calculations [PDF]

open access: yes
A model of viscoelastic deformations associated with earthquakes is presented. A strike-slip fault is represented by a rectangular dislocation in a viscoelastic layer (lithosphere) lying over a viscoelastic half-space (asthenosphere).

Heterogeneous rheology controlled postseismic deformation of the 2011 Tohoku‐Oki earthquake

open access: yesGeophysical Research Letters, 2016
Using two‐dimensional finite element modeling, we reproduced the observed postseismic deformation of the 2011 Tohoku‐Oki earthquake. Our model, which accounts for the lithosphere‐asthenosphere boundary and weak zones beneath volcanoes, was able to ...
