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

Journal 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

Journal 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 ...

A statistical investigation into relationships between the IIE irons and the ordinary, F and “HH” chondrites

Meteoritics &Planetary Science, Volume 60, Issue 10, Page 2376-2400, October 2025.
Abstract It has been proposed that IIE iron meteorites formed through impact processes on a parent body that was composed of either the H chondrites or a much‐debated fourth ordinary chondrite group, the HH chondrites. To resolve this debate, we have compiled a large dataset for the ordinary chondrites, low‐fayalite ungrouped chondrites, and IIE irons,

Löpönvaara: A new phosphorus‐rich iron meteorite from Finland

Meteoritics &Planetary Science, Volume 60, Issue 10, Page 2442-2457, October 2025.
Abstract Löpönvaara is a rare new phosphorus‐rich iron meteorite find from Löpönvaara, Finland. The ~164 g meteorite was discovered in 2017 from the same area as the ungrouped Lieksa pallasite. Löpönvaara was classified as an ungrouped iron meteorite due to its unusually high concentration of P (>4 wt%), coupled with a moderate concentration of Ni (~11
