Modeling Geoid and Dynamic Topography From Tomography‐Based Thermo‐Chemical Mantle Convection

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Mantle convection causes the most important contribution to the geoid and dynamic topography. With mantle density inferred from high‐resolution tomography models and numerical methods solving the governing equations of viscous mantle flow, the modeled geoid can fit the observations well.

Scandinavia: A former Tibet?

Geochemistry, Geophysics, Geosystems, 2013
The Himalaya and the Tibetan Plateau are uplifted by the ongoing northward underthrusting of the Indian continental lithosphere below Tibet resulting in lithospheric stacking. The layered structure of the Tibetan upper mantle is imaged by seismic methods,

Sound Velocities and Structural Transitions of Endmember and Fe, Al, Mg, Ti‐Bearing CaSiO3 Glasses Up to 23 GPa

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The study of silicate glasses is important to understand the physical and chemical properties of silicate melts under high‐pressure conditions relevant to planetary interiors. We conducted in situ Brillouin spectroscopy measurements on two endmember, low‐impurity CaSiO3 glasses and one Fe, Al, Mg, Ti‐bearing CaSiO3 glass up to 23 GPa.

Numerical Modeling of Purely Active (Plume‐Produced) Continental Rifting and Break‐Up

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract In contrast to the traditional mechanism of passive continental rifting (driven by far‐field tectonic forces), the active rifting‐to‐break‐up processes (caused by rising mantle plumes) are still poorly understood. However, most episodes of fragmentation of the last supercontinent Pangea were relatively shortly preceded (within ∼10 Myr) by the ...

Neogene plate tectonic reconstructions and geodynamics of North Island sedimentary basins: Implications for the petroleum systems [PDF]

, 2006
Although the modern Australia-Pacific plate boundary through New Zealand is relatively straight, there have been significant changes in its geometry during the Neogene. Within the North Island sector there has been a fundamental transition from an Alpine

Density of Sodium Aluminosilicate Melts Along the NaAlSiO4‐NaAlSi3O8 Join at High Pressure: In‐Situ Measurements and Re‐Calibration of a Modified Hard‐Sphere Equation of State For Silicate Melts

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Silicate melts play a crucial role in planetary differentiation. The density contrast between silicate melts and the surrounding solid residue exerts a primary control on many magmatic processes. However, direct measurements of the density of silicate melts at high pressure (P) and temperature (T) conditions remain challenging, particularly ...
