Controls on Iron‐Redox State in Martian Magmas Quantified by Mössbauer Spectroscopy, Colorimetric Wet Chemistry, and XANES Spectroscopy

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract To elucidate the relationship between oxygen fugacities (fO2) recorded in martian basalts and redox processes in the martian interior, superliquidus 100‐kPa furnace experiments on a composition similar to Humphrey (Adirondack basalt) were conducted at variable fO2 and temperature. Quenched glasses were analyzed by EPMA, Mössbauer spectroscopy,

Single Piezometric Stress Preserved in Strained Feldspar and Quartz From Intracontinental Lower Crust

open access: yesTectonics, Volume 45, Issue 3, March 2026.
Abstract The strength of the intracontinental lower crust exerts a primary control on regional‐scale deformation during continent‐continent collision. Because of the nominally anhydrous nature of much of the intracontinental lower crust, it is generally considered to be more viscous than lower crust in hydrated tectonic margins.

The Paleo‐Tethys Suture Zone in the Afghan Hindu Kush‒Pamir: Geo‐Thermochronology, Geochemistry, Tectonics

open access: yesTectonics, Volume 45, Issue 3, March 2026.
Abstract In the Afghan Hindu Kush, the 223–209 Ma (≤800°C) Salang batholith is part of the Silk‐Road magmatic arc that was built on ∼40‐km‐thick Turan‐Karakum block continental crust. The batholith constitutes the hanging wall of the Herat‐Panjshir‐Badakhshan—the Paleo‐Tethys—suture zone, vestige of the subducted Paleozoic‐early Mesozoic Paleo‐Tethys ...

High‐energy synchrotron X‐ray multimodal computed tomography: enabling multiscale materials characterization at NSLS‐II

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 2, Page 531-542, March 2026.
The development of multimodal X‐ray computed tomography capabilities, including imaging, fluorescence, diffraction, and scattering, at the 28‐ID‐2 beamline of the National Synchrotron Light Source II is described.We report the commissioning of a multimodal computed tomography experimental setup at the 28‐ID‐2 (XPD) beamline of the National Synchrotron ...
