Constraining the Hydration of Clay Minerals and Abundances of Amorphous Phases in Gale Crater, Mars
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Both water and organic matter are required for the development and persistence of life. Phyllosilicates (clay minerals) have high surface areas that easily sorb water and organic matter. The Curiosity rover has investigated several hundred meters of stratigraphy in Gale crater, including where clays were detected from orbit.

Aqueous alteration in C2‐ung Bells through the analysis of carbonates – Does a CR origin ring true?
Meteoritics &Planetary Science, Volume 61, Issue 5, Page 927-941, May 2026.Abstract Bells is an ungrouped carbonaceous chondrite that has in recent years been proposed as a CR‐an. This link to CR chondrites has previously been identified through the analysis of anhydrous silicates, for example, oxygen isotopic compositions of olivine (Marrocchi et al., 2023).

Investigation of Thermoluminescence Characteristics and Kinetics of Natural Obsidian
Luminescence, Volume 41, Issue 4, April 2026.Thermoluminescence (TL) properties of natural obsidian from the Aksaray region were investigated under beta irradiation. The study identifies optimal grain size, evaluates kinetic parameters via Tm–Tstop and computerized glow curve deconvolution (CGCD) methods, and demonstrates the material's potential for low‐dose environmental and personal radiation ...
