The Boulder‐Rich Blocky Unit of the Western Jezero Upper Fan: Discriminating Olivine and Pyroxene Compositions and Constraining Provenance

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The boulder‐rich unit of the Upper Western Fan in Jezero crater, Mars is the youngest preserved unit of the fan stratigraphy. Understanding boulder compositions, distribution, and textures is critical for constraining their emplacement, provenance, and the depositional history of the Western fan.

Magnetic Properties of Martian Impact Basins Including the Effect of Mantle Excavation

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The weak magnetism of many impact basins on Mars has historically been interpreted as evidence of the martian dynamo's cessation before ∼4.0 Ga. However, expected magnetic properties of these impact basins are poorly known because basin formation exhumes and recrystallizes mantle material, which has not been sampled by martian meteorites ...

Hubble Space Telescope observations of Mars [PDF]

Hubble Space Telescope (HST) afforded the possibility of resolving features as small as 100 km on the Martian surface even when it is at the far point of its orbit. Therefore it is ideally suited for monitoring seasonal changes on the red planet.

Ultraviolet Photooxidation of Carbonate‐Bearing Aqueous Ferrous Iron Within Open and Closed Experimental Systems—Implications for Sunlit Surface Water Bodies on Early Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Ultraviolet (UV) photooxidation has been considered a viable pathway to oxidize aqueous ferrous iron expected to have been present in early Martian surface waters. This reaction has been proposed to have created iron mineral deposits in Meridiani Planum as well as Gale Crater and would have affected chemical conditions such as pH and dissolved

Computer modeling of the mineralogy of the Martian surface, as modified by aqueous alteration [PDF]

Mineralogical constraints can be placed on the Martian surface by assuming chemical equilibria among the surface rocks, atmosphere and hypothesized percolating groundwater.

Dark‐Toned Halite‐Enriched Veins Above the Marker Band Record a Drying Environment in Gale Crater

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The Martian surface preserves evidence of a global climate transition from wetter to drier conditions, but the nature of the fluids involved in this evolution remains poorly constrained. In Gale crater, the clay‐sulfate transition and presence of evaporite mineral assemblages can provide insights into the properties of these fluids and the ...
