Geosciences PhD student working on thrust belt kinematics in the northern US Cordillera and southern central Andes. Structural geology, tectonics, thermochronology.
Metamorphic core complexes (MCCs) are a product of crustal extension, but their dynamics are still debated. Early research suggests that the formation of MCCs in the western USA was due to gravitational collapse of crust that had been thickened during Cordilleran orogenesis. However, the instability of overthickened crust alone cannot explain the d...
Despite the widespread occurrence and economic significance of gold placer deposits, modern provenance studies of placer sediments remain largely qualitative. This study applies detrital zircon (DZ) geochronology to determine the source of zircon in placer deposits. We then evaluate the provenance of the zircon to assess whether the gold might have...
Detailed geologic mapping of a 1:24K quadrangle provides insight into the Anaconda metamorphic core complex (AMCC) footwall structure and records previously undocumented cross-cutting relationships. The dominant structure in the map area is the Anaconda detachment. The detachment dips shallowly southeast (~12-15°), separating crystalline and metase...
The timing of deformation within and adjacent to the Helena salient of west-central Montana is poorly constrained relative to other segments of the Sevier fold-and-thrust belt. The Little Belt Mountains (LBM) are an intraforeland uplift that is juxtaposed with the eastern edge of the thrust belt and situated along the northern Belt Supergroup basin...
