The "Yin-Yang Grid": An Overset Grid in Spherical Geometry

, 2004
A new kind of overset grid, named Yin-Yang grid, for spherical geometry is proposed. The Yin-Yang grid is composed of two identical component grids that are combined in a complemental way to cover a spherical surface with partial overlap on their ...

Sound Velocities of FeO‐Bearing Ringwoodite and Majorite: Implication for Martian Mantle Seismic Profiles

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Compressional and shear wave velocities (Vp, Vs) of candidate Martian deep‐mantle minerals, FeO‐rich ringwoodite ((Mg0.66Fe0.34)2SiO4) and majorite (Mg0.75Fe0.10Al0.26Ca0.07Si0.84O3), were measured up to 25 GPa and 700 K using Brillouin light scattering coupled with externally‐heated diamond anvil cells.

Origin and thermal evolution of Mars [PDF]

The thermal evolution of Mars is governed by subsolidus mantle convection beneath a thick lithosphere. Models of the interior evolution are developed by parameterizing mantle convective heat transport in terms of mantle viscosity, the superadiabatic ...

Simultaneous inversion of mantle properties and initial conditions using an adjoint of mantle convection [PDF]

, 2008
Through the assimilation of present-day mantle seismic structure, adjoint methods can be used to constrain the structure of the mantle at earlier times, i.e., mantle initial conditions.

Mountain building and mantle dynamics [PDF]

, 2013
International audienceMountain building at convergent margins requires tectonic forces that can overcome frictional resistance along large-scale thrust faults and support the gravitational potential energy stored within the thickened crust of the orogen.

A multiscale approach to evaluate the effect of different extraction and pre‐treatment methodologies on physicochemical properties of cashew (Anacardium occidentale L.) nut shell liquid

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 2, Page 266-275, February 2026.
Abstract BACKGROUND Cashew nutshell liquid (CNSL) is an agro‐industrial residue from cashew production that has gained relevance due to its possibilities to generate valuable by‐products. Although lab‐scale CNSL extraction has been studied in terms of yield and energy efficiency, the effect of industrial‐scale extraction and nut pre‐treatment methods ...

Symmetry and plate-like convection in fluids with temperature-dependent viscosity [PDF]

, 2014
We explore the instabilities developed in a fluid in which viscosity depends on temperature. In particular, we consider a dependency that models a very viscous (and thus rather rigid) lithosphere over a convecting mantle.

Lithospheric Delamination Below the North American Midcontinent Ceased Subsidence in Cratonic Basins

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Cratonic lithospheres carry a long history of tectonic modifications that result in heterogeneous structures, as revealed by an increasing number of geophysical observations. The existence of cratonic basins indicates protracted periods of tectonic modification, causing subsidence within global continental interiors.

Spatial distribution and possible origin of the high velocity lower crust in the northern margin of the South China Sea

Geoscience Letters
High-velocity lower crust (HVLC) near the continent–ocean transition zone is significant for recording magmatic activity and early rifting history and is likely to be sourced from various types of magma supplies, including passive decompression melting ...

Impact‐Generated Mixing, Melting and Vaporization of the Early Earth's Crust

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Earth's primary accretion was followed by a protracted flux of interplanetary collisions by leftover planetesimals. The effects of the largest collisions—with bodies possibly exceeding 1,000 km diameter—would have been devastating for terrestrial near‐surface environments.
