Stratigraphy and Provenance of the Kekiktuk Conglomerate and Associated Carboniferous Units in the Northeastern Brooks Range of Alaska
Undergrad Thesis Work
Advisor: Dr. Justin Strauss
During undergrad at Dartmouth, I was part of a team exploring the Devonian-Carfoniferous tectonic history of the northeastern Brooks Range of Arctic Alaska, and specifically a regional transition from a contraction to extension. My contribution included the first investigation of the Kekiktuk Conglomerate and associated units in the field area, the headwaters of the Sheenjek River in the Brooks Range. These units were deposited during this critical tectonic transition, and I performed a paleoenvironmental analysis which helped shed light on the larger setting in which these rocks were deposited. My work included field mapping, measuring and analyzing stratigraphic section, preparing samples in the lab for thin section and other analyses (geochronology and geochemistry), and a petrographic analysis.
I presented a poster of this work at the 2023 GSA Cordilleran Section Meeting as well as the 2023 Wetterhahn Science Symposium.
