Congratulations to Nick Cunetta who successfully defended his M.S. thesis research! Nick mapped high-grade amphibolite and blueschist units in the Easton terrane combined with garnet geochronology to determine the timing of subduction initiation and the deformation of early subduction zone rocks. Nick's work revealed a complex deformation and metamorphic …

Congratulations to Emily Gates on her M.S. thesis!
Congratulations to Emily Gates who successfully defended her M.S. thesis research! Emily combined structural mapping, microstructural analysis, and Raman thermometry to demonstrate strain localization along unit boundaries in the Easton metamorphic suite. Her work supports models for progressive acretion of separate regional blueschist units during prolonged subduction. As part …

Congratulations to Katie Lang who successfully defended her M.S. thesis research! Katie's thesis work applied structural mapping and detrital zircon geochronology to test regional correlations between blueschist facies units in the Northwest Cascades and compare the timing of subduction accretion events with other Jurassic-Cretaceous subduction zones along strike in …

Our research group presented a series of talks and posters at the recent 2023 GSA Cordilleran meeting in Reno, NV. The presentations centered on our work to understand the record of Jurassic-Cretaceous subduction zone metamorphism and deformation preserved in the Northwest Cascades. Our research was funded by NSF-EAR Tectonics award …

After two years of teaching online and remote versions of field camp, this summer we returned to six weeks of in person geology across Idaho and Montana. This year also coincided with my first year teaching the course in Montana, where we explored a variety of geologic problems in Dillon …

Former M.S. student Andy Tholt (now at UC Berkeley) has published his thesis research in Geosphere. In this work, Andy combined field mapping with metamorphic petrology and garnet and monazite geochronology to constrain the boundaries between different tectonic domains in the Famatina margin of Argentina. The results revise existing …
