We are conducting a large integrated experiment to determine the crustal and upper mantle structure beneath the High Lava Plains of eastern Oregon, interpret the imaged structure with input from geochemical, geochronologic, and petrologic data on the young surface volcanism, and combine these observational datasets with geodynamic modeling in order to understand why this minimally extended part of the Basin and Range has been the most volcanically active region of North America in the late Cenozoic. The thesis of this project is that the proposed region of study represents one of the most accessible, yet least understood and least geophysically investigated, examples worldwide of regionally extensive continental intraplate magmatism
