Evolution of Terrestrial Planetary Bodies and Implications for Habitability

open access: yesReviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.

Mineralogy and matrix composition of CR chondrites Renazzo and EET 87770, and ungrouped chondrites Essebi and MAC 87300 [PDF]

open access: yes
The fine-grained mineralogy of the matrix of two CR chondrites, Renazzo and EET 87770, and the ungrouped (but possible related) Essebi and MAC 87300 chondrites was characterized using standard microprobe (focussed beam) and transmission electron ...

Confronting Episodic vs. Continuous Heat Sources in Long‐Lived Hot Orogens: Insights From Petrochronological Studies in the Nova Venecia Complex, Araçuaí Orogen (SE Brazil)

open access: yesJournal of Metamorphic Geology, Volume 43, Issue 9, Page 863-890, December 2025.
ABSTRACT Orogenic belts that sustain elevated temperatures at intermediate crustal depths for tens of millions of years are known as hot orogens. The evolution of these hot orogens is largely influenced by thermal maturation, primarily driven by the distribution of heat‐producing elements (HPEs), such as K, Th and U in the overthickened crust.

Single chondrule K-Ar and Pb-Pb ages of Mexican ordinary chondrites as tracers of extended impact events

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
There is a good consensus about the age of the most primitive materials in the Solar System represented by carbonaceous chondrites. From these, a canonical age of the Solar System of 4567 Ma has been defined.

Sedimentary record of submarine gravity‐flow events in the southern Ryukyu forearc during the last 200 000 years: Archive of mega‐earthquakes and tsunamis

open access: yesSedimentology, Volume 72, Issue 7, Page 2323-2360, December 2025.
ABSTRACT Despite high convergence velocity, the southern Ryukyu subduction has relatively low and sparse instrumental seismicity, in contrast with the Yaeyama Islands, hit by huge tsunamis over the last few thousand years. This study explores the potential of deep marine sediments to record past large earthquakes and tsunamis.

Mid-infrared Measurements of Ion-irradiated Carbonaceous Meteorites: How to Better Detect Space Weathering Effects

open access: yesThe Planetary Science Journal
Remote sensing study of asteroids will soon enter a new era with an increasing amount of data available thanks to the JWST, especially in the mid-infrared (MIR) range that allows identification of mineral species.
