Phanerozoic Onset of Massive Continental Weathering

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Continental weathering acts as a nexus of global biogeochemical cycles yet its long‐term evolution remains unclear. Here we show that continental weathering may not have operated on a massive scale until the early Paleozoic based on a large‐number data compilation of mudstone geochemistry.

Soil hydraulic properties, mineralogical alteration and pore formation in Regosols from southern Brazil [PDF]

Revista Brasileira de Ciência do Solo
Regosols (Neossolos) are soils with use limitations mainly related to effective depth, abundant presence of rock and saprolite fragments, and frequently high slope gradients; besides that, they represent a new agricultural frontier for grain production ...

Interactions of rare earth elements with living organisms and emerging biotechnical applications

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1251-1274, September 2025.
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

Determination of the Dynamic Angle of Repose of Lunar Regolith Simulants

Geosciences
The determination of the dynamic angle of repose (DAR) of lunar regolith simulants is essential for modeling material behavior during in situ resource utilization (ISRU) processes and lunar surface operations.

A Goniometric System for Photometric and Polarization Measurements of Planetary Regolith Analogs

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract The Planetary Surface Texture Laboratory at the Johns Hopkins University Applied Physics Laboratory is a facility for the study of the photometric and polarization behavior of regolith analogs using an ∼1.5‐m‐radius arc goniometer system. This system characterizes the photometric and polarization response of granular materials (planetary ...

Multiple Episodes of Fluid Alteration in Jezero Crater Indicated by MIST Mineral Identifications in PIXL XRF Data From the First 1100 Sols of the Mars 2020 Mission

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract The Mineral Identification by Stoichiometry (MIST) algorithm can identify mineral species in geochemical data sets. MIST is applied to X‐ray fluorescence chemical analyses from the Planetary Instrument for X‐ray Lithochemistry (PIXL) on the Mars 2020 Perseverance rover to identify mineral phases in abraded rock targets at Jezero crater.

A Comprehensive Framework for Assessing Terrestrial Analogue Field Sites for Ocean Worlds

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Field studies at terrestrial analogue sites represent an important contribution to the science of ocean worlds. The value of the science and technology investigations conducted at field analogue sites depends on the relevance of the analogue environment to the target ocean world.
