Compositional and Physical Gradients in the Magmas of the Devine Canyon Tuff, Eastern Oregon| Constraints for Evolution Models of Voluminous High-silica Rhyolites
<p> Large-volume silicic ignimbrites erupt from reservoirs that vary in composition, temperature, volatile content and crystallinity. The 9.7 Ma Devine Canyon Tuff (DCT) of eastern Oregon is a large-volume (>250 km<sup>3</sup>), compositionally zoned and variably welded ignimbri...
