Accessory minerals: a provenancing tool for steatite quarries

open access: yesArchaeometry, Volume 67, Issue 5, Page 1212-1229, October 2025.
Abstract Steatite has been a widely traded material across a range of archaeological contexts. Yet, challenges inherent to determining its provenance limits our understanding of the networks and mechanisms of its exchange. We present a robust new accessory mineral provenancing “fingerprint” method based their specific growth history.

Tectonothermal Evolution of the NW Wyoming Province: Insights From Coupled Garnet Lu‐Hf and Sm‐Nd Geochronology

open access: yesJournal of Metamorphic Geology, Volume 43, Issue 8, Page 839-862, October 2025.
ABSTRACT Understanding how Paleoproterozoic orogenic processes shaped the assembly of Laurentia remains a critical puzzle in deciphering Earth's ancient tectonic history. To address this challenge, the Montana metasedimentary terrane in the northwest Wyoming Province, which preserves a complex record of multiple metamorphic episodes, provides a unique ...

Fluid or Melt? Distinguishing Syn‐Deformational Interaction Pathways

open access: yesJournal of Metamorphic Geology, Volume 43, Issue 8, Page 810-838, October 2025.
ABSTRACT Understanding whether deformation occurred in the presence of aqueous fluid or silicate melt is crucial for interpreting ductile shear zones, impacting their thermal and geochemical evolution, and having rheological consequences. To identify the syn‐deformational fluid type, we investigate contrasting shear zones active during the Alice ...
