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.

Rethinking “Prebiotic Chemistry”

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract In origins‐of‐life research, the term “prebiotic chemistry” is commonly used to describe processes thought to be related to or required for the emergence of life. However, it suffers from several potential drawbacks that have caused the present group of authors to rethink their usage of the term.

Isotopologue Ratios Identify 13C‐Depleted Biomarkers in Environmental Samples Impacted by Methane Turnover

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 22, 30 November 2025.
ABSTRACT Rationale The stable carbon isotopic composition (δ13C) of individual lipids is of great value in studying carbon cycling. Among those, microbial lipids in sediments impacted by high methane turnover stand out due to their uniquely depleted isotopic fingerprint.

High-resolution decadal-scale eruption age dating of young oceanic basalts at an active hydrothermal vent site

open access: yesFrontiers in Geochemistry
Here we report (210Pb/226Ra), (226Ra/230Th), (230Th/238U) and (234U/238U) disequilibria for eleven lavas from the ABE vent site in the Lau Basin. Most ABE lavas have (210Pb/226Ra) > 1 and (226Ra/230Th) > 3. These results indicate that most of these
