Automated Mineral Identification and Rock‐Type Classification of Lunar Mare Basalts Using SEM Images

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract We present an automated system for identifying minerals and classifying rock types in Apollo lunar mare basalts using scanning electron microscopy (SEM) imagery. Mineral segmentation is based on a U‐Net architecture, supplemented by two scale‐aware models designed to incorporate pixel size information.

Abiotic Iron Precipitation and Its Influence on Groundwater Flow in Subterranean Estuaries Under Tidal Forcing

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Within subterranean estuaries (STEs), Fe2+ from freshwater is oxidized by O2(aq) from seawater to form Fe precipitates and low‐permeability zones (“Fe curtains”). Tidal fluctuations generate an upper saline plume (USP) above the saltwater wedge (SW), enhancing freshwater–seawater mixing and associated chemical reactions.

Structurally‐Controlled Permeability Evolution and Mineralization in Geothermal Caprocks: The Fenice Capanne Mining District (Southern Tuscany, Italy)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The Neogene mineralized region of the Colline Metallifere in southern Tuscany (Italy) provides a natural laboratory to investigate feedback between fluid–rock interaction, structurally controlled fluid flow, and hydrothermal ore mineralization.

Oxygen Fugacity Buffers and an Interactive Calculator

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Oxygen fugacity buffers are equilibrium phase assemblages that constrain the chemical potential of oxygen. They may be coexisting minerals or fluids, or their metastable extrapolations. Oxygen fugacity values vary as a function of pressure and temperature, such that raw numbers often have little interpretive value.

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

Journal 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.
