5:30 pm social hour

7:00 pm presentation

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.
