Stratigraphy of Carbonate‐Bearing Rocks at the Margin of Jezero Crater, Mars: Evidence for Shoreline Processes?

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Martian carbonate‐bearing rocks are compelling targets for exploration because they preserve detailed records of past aqueous processes, climate, and habitability. The Margin unit in Jezero crater is a distinct olivine‐ and carbonate‐bearing unit stratigraphically underlying the western fan, lining the inner margin of the western crater rim ...

Formation and Alteration of Olivine‐Carbonate Rocks Within Jezero Crater as Constrained by In Situ Visible/Near‐Infrared Multispectral Images

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Olivine‐ and carbonate‐bearing rocks are key exploration targets on Mars because of the information they can provide about magma evolution and source characteristics, implications for surface water availability and climate, and their biosignature preservation potential.

Ferromagnesian Clay Diversity Across Mars' Crustal Dichotomy: A Window Into Early Aqueous Environments

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Extensive research over the past two decades has shown that early Mars likely had a warmer, wetter climate with widespread water activity. Ferromagnesian (Fe,Mg‐rich) clay deposits are compelling markers of these ancient environments, helping reconstruct Mars' hydrologic evolution, assess past habitability, and guide future exploration.

The New Space Race Era: The Exogeoheritage Challenge and Its Conservation

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract The escalating pace of space exploration has ushered in a new era reminiscent of the space race of the 1960s. However, the discourse on exogeoconservation—the protection of geological heritage—now demands a prominent place in decision‐making processes.
