Assessing controls on forearc basin subsidence

In collaboration with Dr. Stephan Graham

Low and high density turbidites, Great Valley Forearc, California

Forearc basins are important sediment archives for understanding continental dynamics because they preserve the tectonic, erosional and magmatic record of convergent margins. However, the tectonic forces that drive subsidence in forearc basins are poorly understood. This research seeks to determine the relative contribution of a variety of end-member subsidence mechanisms that act on forearc basins by using the California Great Valley forearc basin as the natural laboratory.

Extracting t-T histories from highly variable zircon He datasets

In collaboration with Dr. William Guenthner

Recent advances in the understanding of He diffusivity in zircon provide new opportunities to extract thermal histories from regions with which experienced multiple and prolonged thermal events using the zircon He method. We are currently working on new thermochronologic constraints on the time-Temperature history of the northern Rocky Mountain region in Wyoming.
