About TeST

Welcome to the home of the Montana State University Tectonic Sedimentology and Thermochronology Laboratory, TeST!

Our group focuses on the evolution of convergent margins by reconstructing paleo-depositional environments and the tectono-thermal history of sedimentary basins and ancient orogens. We are a field based research group, with active studies in Tibet, Montana, and California. In addition to field based techniques, we apply analytical techniques such as U-Pb geochronology, (U-Th)/He and fission track thermochronology, and sandstone petrography to study the geologic past!


New Publication (August 2019): Check out a new paper in Geology: “A Late Cretaceous trans-arc river that drained the proto-Tibetan Plateau”. This work is in collaboration with Dr. Andrew Laskowski (MSU), Dr. Ding Lin and Dr. Fulong Cai (Chinese Academy of Sciences). doi:10.1130/G46xxx.1 (Open access).

New Publication (June 2019): Check out my new paper in collaboration with Dr. Kathy Surpless: “The birth of a forearc: The basal Great Valley Group, California, USA”, Geology, doi: https://doi.org/10.1130/G46283.1 (Open access).

DAAD Fellowship: Dr. Orme was awarded a fellowship through Deutscher Akademischer Austauschdienst (German Academic Exchange Program) to work at the University of Potsdam this Summer. I will be collaborating with Dr. Edward Sobel on apatite fission track thermochronology. Danke dir DAAD!
