Implications of Laser‐Induced Polymorphism Transformations in Bismuth(III) Vanadate Raman Spectroscopy Characterization

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 5, Page 761-765, May 2026.
Accurate crystalline phase identification is critical for optimizing the performance of BiVO4 in various applications. Raman spectroscopy is a useful technique for these purposes, but it should be noted that laser power during Raman analysis can induce polymorphic transitions, affecting phase interpretation.

Interior Rifting Coupled With Peripheral Subduction in the Rodinia Supercontinent: New Insights From the Tarim Craton

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract After assembly, supercontinents are shaped by internal rifting and peripheral subduction. However, the geodynamic relationship between these two processes and their respective contributions to supercontinent breakup remain poorly understood.

Key New Evidence for the Hainan Mantle Plume Head: Ongoing Formation of a Large Igneous Province?

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The process‐based surface magmatic expression of mantle plumes is typically a large igneous province (LIP) induced by the mantle plume head, followed by subsequent age‐progressive volcanic tracks resulting from plate drifting above the plume tail.

Hornblendite in the Lower Crust: A Possible Source for Porphyry Cu Deposits

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Lower crustal sulfide‐bearing Cu‐rich cumulates, mainly occurring as hornblendite, have been proposed as a critical source component for the development of giant porphyry Cu deposits (PCDs); however, their mineralogical and geochemical nature remain elusive.
