Microstructural Controls on Geothermal Reservoir Host Rock Responses to Elevated Pressures and Temperatures

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Rock microstructure controls geothermal fluid flow within reservoirs hosted in active volcanic environments and as such it is necessary to constrain the microstructural evolution of rocks at elevated pressure and temperature conditions. Despite Andean geothermal systems hosting numerous high enthalpy geothermal plays, there remains a paucity ...

Deciphering the “Missing Xenon Paradox” in Celestial Bodies: A Multifaceted Perspective Toward Demystifying This Enigma

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Xenon (Xe) is a heavy noble gas with intriguing chemical properties, such as having several stable isotopes and the ability to form compounds under extreme conditions. Despite the predictions based on cosmochemical models that suggest xenon should be relatively abundant in planetary reservoirs, empirical data indicate a significant depletion ...

Electrical properties of vitreous As2(Se,Te)3 before and after annealing

open access: yesJournal of Non-Crystalline Solids, 1972
Abstract Detailed measurements of the electrical conductivity versus temperature were performed on vitreous As 2 (Se,Te) 3 alloys before and after annealing at 100°C. The ln σ versus 1/ T plots showed a slight departure from linearity with the slope decreasing continuously with decreasing temperature.
