TL;DR: This work uses high-resolution finite-element models based on rheological data of the lithosphere to investigate the role played by water on initiating subduction and indicates that subduction can proceed by a double feedback mechanism (thermoelastic and thermal-rheological) promoted by lubrication due to water.

TL;DR: In this paper, the authors investigated a weak, but persistent low S-velocity anomaly in the upper mantle beneath the US East Coast, which they interpreted as relatively cool, subducted Farallon lithosphere.

TL;DR: In this article, the authors present a fully coupled energy approach to investigate the important problem of ductile faulting within the lithosphere, where the perturbations diffuse through conduction while the model is subject to constant velocity pure shear boundary conditions.

TL;DR: In this article, the authors investigated the influence of both density and viscosity on the effectiveness of recycling of oceanic crust into the lower mantle and found that the crustal component of slabs may be trapped at 670 km depth, leading to a garnet enriched transition zone.

TL;DR: In this paper, the authors employed a three-dimensional compressible convection model to study the dynamics of phase transitions in the Martian mantle and found that a large core model with two exothermic phase transitions, the olivine to β-spinel and the β- to γ -spinel transition, and a small core model including also the endothermic spinel to perovskite transition were considered.
