Геодинамика и тектонофизика, 2015 The paper presents the first tectonophysical reconstruction of initial divisibility of the protolithosphere as a result of convection in the cooling primitive mantle. Initial division of the protolithosphere into separate masses, i.e.

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.Abstract Water ice is an important rock‐forming mineral, both on the Earth and on various extraterrestrial bodies. Naturally occurring ice is often “dirty”–an intimate mixture with harder mineral grains, which can have significant effects on the bulk properties of the aggregate. We have used neutron powder diffraction, with in situ triaxial deformation,

Tectonics, Volume 45, Issue 9, September 2026.Abstract The Fennoscandian Shield potentially hosts the longest continuous habitable conditions for Earth's deep biosphere. Billion‐year equilibrium freeboard conditions of cratons and the longevity of deep biosphere microbial communities are directly related through the thermal histories of rocks that host these communities.

Origin of Long‐Wavelength Variations in Crustal Thickness on Rocky Planets
Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract Long‐wavelength crustal thickness variations are observed on telluric planets, particularly on Mars and the Moon whereas Mercury appears to lack such variations. They may stem from two early‐stage positive feedback mechanisms that can emerge in stagnant‐lid planets.

The energetics of melting fertile heterogeneities within the depleted mantle [PDF]
To explore the consequences of mantle heterogeneity for primary melt production, we develop a mathematical model of energy conservation for an upwelling, melting body of recycled oceanic crust embedded in the depleted upper mantle.

Controls on Solar Wind Entry Identified Through Wind–ACE Heavy‐Ion Diagnostics
Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract Solar wind (SW) entry into the magnetosphere occurs through several mechanisms, but their dependence on the properties of different ion species is unknown. We compare measurements from Wind‐STICS (magnetosphere) with ACE‐SWICS (L1) to test for any preferential entry between He2+ and SW heavy ions.

Stability of (Mg,Fe)SiO3 perovskite and the structure of the lowermost mantle [PDF]
, 1992 Thermodynamic analysis shows that (Mg,Fe)SiO3 perovskite is stable throughout the likely pressure, temperature and compositional regime of the Earth's mantle.

One-dimensional physical reference models for the upper mantle and transition zone: combining seismic and mineral physics constraints [PDF]
One-dimensional seismic reference models are known to be a nonunique solution to global seismic data, hampering an interpretation in terms of physical structure. Here we test the compatibility of the simplest hypothesis of a mantle convecting as a whole,

Journal of Geophysical Research: Machine Learning and ComputationMantle convection drives the solid Earth, powering plate motions, volcanism, and earthquakes while regulating planetary heat loss. Reconstructing its history is hampered by sparse, noisy observations concentrated near the surface and the present day ...
