Trace Element Transport and Deposition During Magmatic Degassing: The Effect on Martian Rocks and Fines

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Martian magmas compositionally resemble those from terrestrial continental hotspot magmatic suites, characterized by low OH and high Cl and S contents. The magmatic gases exsolved from such magmas transport a variety of metal complexes and, upon cooling, precipitate vapor‐deposits into vugs and fractures within rocks and on the surfaces of ...

Radar Polarimetry in Glaciology: Theory, Measurement Techniques, and Scientific Applications for Investigating the Anisotropy of Ice Masses

open access: yesReviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...

Petrologic constraints on the pressure, temperature, time and composition of the Martian interior [PDF]

open access: yes
Petrologic analysis of surface samples has been used to deduce pressure and temperature conditions existing in the crust and upper mantle at specific times in the Earth's history, as well as to estimate the chemical and mineralogical composition of the ...

Oxychlorine Species on Mars: A Review

open access: yesReviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

The Usefulness of NotebookLM's Audio Overview for Planetary Scientists

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The availability and use of artificial intelligence (AI) tools has increased substantially in recent years. NotebookLM was released in 2023 and is an AI tool with the capability to generate text summaries of input material. In 2024, an “Audio Overviews” feature was released that can generate podcast‐style audio files of the summarized material.
