Basalt and Rhyolite Volcanism of the High Lava Plains of Oregon: Timing, Tectonics and Petrology

Dr. Anita Grunder, Associate Dean of Academic Programs, Oregon State University

The High Lava Plains is an enigmatic province between the hot-spot related Steens Basalts and the subduction-related Cascades. Dr. Grunder will explore the implications of the westward age progression of rhyolites and the effect of protracted magmatism on the composition of the volcanic rocks and the crust.

Dr. Anita Grunder earned her BS at Berkeley, and her PhD at Stanford. She has been at OSU since 1986. Her research is in volcanic rocks as a probe for crustal magma process in time and in diverse tectonic settings.
