P and S Wave Anisotropic Tomography of the Banda Subduction Zone
Geophysical Research Letters, 2023 In subduction zones with slab‐slab interactions, the pattern of mantle convection is very complex and still unclear. In this study, we jointly invert a large number of P and S wave arrival time data of local earthquakes for 3‐D isotropic and anisotropic ...

On the evolution of the water ocean in the plate-mantle system
Progress in Earth and Planetary Science, 2018 Here, we investigate a possible scenario of surface seawater evolution in the numerical simulations of surface plate motion driven by mantle dynamics, including thermo-chemical convection and water migration, from the early to present-day Earth to ...

On the Role of Rheological Memory for Convection‐Driven Plate Reorganizations
Geophysical Research Letters, 2022 Understanding the temporal variability of plate tectonics is key to unraveling how mantle convection transports heat, and one critical factor for the formation and evolution of plate boundaries is rheological “memory,” that is, the persistence of weak ...

Geochemistry, Geophysics, GeosystemsMineral phase transitions can either hinder or accelerate mantle flow. In the present day, the formation of the bridgmanite + ferropericlase assemblage from ringwoodite at 660 km depth has been found to cause weak and intermittent layering of mantle ...

Intraplate Seamounts as a Window into Deep Earth Processes [PDF]
Oceanography, 2010 Seamounts are windows into the deep Earth that are helping to elucidate various deep Earth processes. For example, thermal and mechanical properties of oceanic lithosphere can be deter-mined from the flexing of oceanic crust caused by the growth of ...

A Simple Thermodynamic Model of the Internal Convective Zone of the Earth
Entropy, 2018 As it is well known both atmospheric and mantle convection are very complex phenomena. The dynamical description of these processes is a very difficult task involving complicated 2-D or 3-D mathematical models.

Tectonic plates in 3D mantle convection model with stress-history-dependent rheology
Earth, Planets and Space, 2020 Plate tectonics is a key feature of the dynamics of the Earth’s mantle. By taking into account the stress-history-dependent rheology of mantle materials, we succeeded in realistically producing tectonic plates in our numerical model of mantle convection ...

MANTLE CONVECTION FOR GEOLOGISTS [PDF]
American Mineralogist, 2014 By Geoffrey F. Davies (2011) Cambridge University Press, U.K., 232 p. $64.00 ISBN 978-0-521-19800-4 (Hardback; e-formats available). Since the plate tectonics model was advanced in the 1960s, mantle convection has been recognized to be at the heart of various activities of the solid Earth like volcanism, continental drift, mountain building, and ...

Geophysical Research LettersA widely accepted global model of glacial isostatic adjustment (GIA) is based on ICE‐6G ice loading and 1D‐viscosity model VM5a, a viscosity profile which remains at odds with mantle convection constraints such as from geoid modeling.

On the impact of true polar wander on heat flux patterns at the core–mantle boundary [PDF]
Solid EarthThe heat flux across the core–mantle boundary (CMB) is a fundamental variable for Earth evolution and internal dynamics. Seismic tomography provides access to seismic heterogeneities in the lower mantle, which can be related to present-day thermal ...
