Fossilised Pioneer Microbialite Communities on Basaltic Substrates at Lake Ashenge (Tigray, Ethiopia): A Model for Ecosystems in Noachian–Hesperian Martian Lakes?

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Microbial communities are strongly controlled by local nutrient availability, frequently resulting from mineral weathering and erosion. On Earth, basaltic rocks in habitable alkaline lacustrine environments are often initially colonised by ‘pioneer’ communities that induce the precipitation of fine‐scale microbial carbonate ‘coatings’; on Mars,

3D Architecture of Kodiak Butte as Evidence of Fluvial or Shoal‐Water Environments in Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Mars 2020 mission has explored depositional environments recorded in a fan‐shaped deposit on the western side of Jezero crater. Kodiak butte is an isolated outcrop of sedimentary rock ∼1 km south of the western fan scarp and may be an erosional remnant of said fan.

Influence of Floodplain Subsurface Composition on Peatland Stream Channel Mobility

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Peatlands are important for the earth's carbon cycle, globally storing the equivalent of two‐thirds of the atmospheric carbon reservoir. The capacity of peatlands to preserve organic matter is influenced by stream‐channel mobility and sediment reworking; however, the nature of these processes is poorly constrained.

Erosional Transfer of Sediment and Organic Carbon Through Time in the Kasaï Basin, Democratic Republic of the Congo

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract African rainforests store large quantities of carbon within below‐ground reservoirs, yet these stocks are threatened by land use and climate disturbances. Previous studies revealed that the peatlands of the Cuvette Centrale in the Congo Basin accumulated less organic carbon (OC) between 7,500 and 2,000 yrs BP (so‐called “Ghost Interval ...

Episodic Arc Behavior in an Accretionary Orogen: Insights From the New England Orogen, Eastern Australia

Tectonics, Volume 45, Issue 10, October 2026.
Abstract Detrital zircon U–Pb geochronology from Triassic–Jurassic basins in the New England Orogen (NEO) constrains sediment provenance and episodic continental arc evolution along the eastern Gondwanan margin. Dominant zircon clusters at 270–230 Ma and 340–300 Ma in these basins were likely sourced from contemporaneous magmatism in the NEO ...
