Mars Alteration on Earth: A Spectroscopic Study of Hydrated Silica and Biomarker Preservation in La Palma Lava Tubes

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Volcanic tubes provide stable environments where unique mineralogical assemblages can form and be preserved, making them valuable terrestrial analogs for Martian studies. This work investigates tree‐like structures within two lava tubes on La Palma Island (Canary Islands, Spain) through a comprehensive geochemical and mineralogical ...

What Earth Erases: Weathering Diversity of Mineral Phases Formed in a Highly Reduced Environment Hosted in Aubrites

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Meteorites serve as an exceptional source of insight into our planet and the Solar System. Most meteorite fragments were recovered hundreds to thousands of years after their fall, and therefore exhibit varying degrees of terrestrial weathering, which has altered or completely removed weather‐sensitive mineral phases.

Minerals in Iron and Titanium Skeletal Textures in Nakhlites MIL 090030, MIL 090136, MIL 090032, and MIL 03346: Comparative Analysis With Terrestrial Analogues From Canary Islands, Spain

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract The presence of minor minerals is a key factor distinguishing meteorite types, as they provide valuable insights into the formation processes, surface conditions, and evolutionary history of their parent bodies. In Martian nakhlites, one of the most distinctive minor phases is iron‐titanium oxides forming characteristic skeletal textures ...

Surface Mineralogy and Hydrological Controls on “Hotspots” of Dust Emission at Etosha Pan, Namibia

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Ephemeral lake beds are globally significant sources of atmospheric mineral dust aerosols, yet emissions from these landforms exhibit considerable spatial and temporal variability. The complex interactions between climatic drivers and surface properties that govern dust emissions remain poorly understood, contributing to uncertainties in model

Late Cenozoic Convergence Between the Pamir and the Tianshan Revealed by Low‐Temperature Thermochronology

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract The Cenozoic India–Eurasia collision drove widespread deformation across Central Asia, culminating in northward indentation of the Pamir and its eventual contact with the South Tianshan. However, the timing and kinematics of Pamir–Tianshan convergence, as well as its influence on regional topography and climate, remain debated. Here, we report
