Unveiling the Crystal Structure of Sanidine: A Polarized Raman and Ab Initio Simulation Exploration

Journal of Raman Spectroscopy, Volume 57, Issue 2, Page 227-238, February 2026.
This study combines polarized Raman spectroscopy and ab initio calculations to assign theoretical vibrational modes to observed spectra. Polarized Raman spectra were collected in six geometries (40–1200 cm−1). Theoretical predictions via DFT show good agreement with experiments, though some discrepancies point to influences like trace elements and ...

Impact‐Generated Mixing, Melting and Vaporization of the Early Earth's Crust

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Earth's primary accretion was followed by a protracted flux of interplanetary collisions by leftover planetesimals. The effects of the largest collisions—with bodies possibly exceeding 1,000 km diameter—would have been devastating for terrestrial near‐surface environments.

Shape Matters: Unlocking Transport Histories in Fine‐Grained Aeolian Sediments With Endmember Modeling of Size–Shape Distributions

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The transport medium, mode, energy, and distance are recorded in the grain‐size and grain‐shape distributions in a sedimentary deposit. While grain‐size analysis has long been used in sedimentology, grain‐shape analysis is increasingly recognized as a valuable tool for reconstructing sedimentary processes and palaeoenvironments.

Testing Volcano Deformation Models Against 3D Seismic Reflection Imagery of Ancient Intrusions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Magma intrusion often drives uplift of the overburden and free surface. Analytical modeling of such surface uplift at active volcanoes allows us to estimate intrusion geometries and positions, as well as volume and pressure changes; these insights have proven critical to forecasting volcanic unrest and eruptions. However, it is rarely possible

Fracture‐Assisted Pressure Solution Creep of Granite: An Example From the Mont Blanc Massif, Western Alps

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Mont Blanc granite, as other deformed granites, has splitting properties attributed to two perpendicular planes: one formed by aligned fractures and the other by aligned micas in foliation planes. It is shown that this microstructure results from ductile deformation with stress‐driven dissolution of quartz and feldspar that passively ...
