Enhancing the properties of high-density oil well cement with Qusaiba kaolinite

Scientific Reports
High-density cement slurries used in oil well cementing often face challenges such as particle settling, poor rheological properties, permeability, and compressive strength degradation, which can compromise zonal isolation and well integrity.

Emerging Themes of Global Dust Research: Linking Physical Processes to Human Health, Safety, and Welfare

GeoHealth, Volume 10, Issue 3, March 2026.
Abstract Dust and dust storms are known to negatively affect human health, safety, and welfare. Most dust‐related studies have previously focused on the physical processes of dust initiation, transport, and deposition at various temporal and spatial scales.

Broadband Dielectric Analysis of Clays: Impact of Cation Exchange Capacity, Water Content, and Porosity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Clay‐rich soils and sediments are key components of near‐surface systems, influencing water retention, ion exchange, and structural stability. Their complex dielectric response under moist conditions arises from surface–ion electrostatics and diffuse double layers that govern transport and retention processes. This study explores the broadband

Multidisciplinary Analyses of Terrestrial Samples Used to Interpret an Inorganic Origin (Anhydrite:Ce3+) for the 304 and 325‐nm Doublet Fluorescence Detected by the Mars 2020 SHERLOC Instrument at Jezero Crater

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Doublet fluorescence at 304 and 325‐nm under deep ultraviolet (DUV) excitation was detected on Mars at Jezero crater by the Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) instrument onboard the Mars 2020 rover Perseverance.

Mineralogical Classification of CRISM Hyperspectral Data Under Uncertainty With Hybrid Neural Networks

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Orbital remote sensing observations are a lynchpin of planetary science research. Hyperspectral infrared spectroscopy in particular is key for planetary mineralogical exploration, for example, CRISM for Mars, as this underpins our understanding of the distribution of specific lithologies and the geological process leading to their formation ...
