Ignimbrite Magma Ascent Rate in the Conduit Determined by Diffusion in Banded Pumice
SOME LIKE IT VISCOUS: INTEGRATED APPROACHES TO UNDERSTANDING SILICIC MELT EVOLUTION, STORAGE, AND ERUPTION I ORAL
volcanology, geochemistry and petrology | 15 december 2021
Anita Grunder, Hannah Shamloo, Kevin Pendergast
Banded pumices are common in ignimbrites. Intricate layering and folding indicates that they form during magma ascent in the chamber and conduit. Base...

An Extension-Induced, Hot-Dry-Reduced Ignimbrite Flare-up in the Cascades Arc: The Deschutes Formation, Central Oregon
A MEDLEY OF TECTONICALLY DRIVEN MAGMATISM IN THE NORTHWESTERN UNITED STATES I ORAL
volcanology, geochemistry and petrology | 13 december 2021
Bradley W. Pitcher, Anita Grunder, Adam J. Kent
Ignimbrite flare-ups are rare events during which the volume and frequency of pyroclastic volcanism is an order-of-magnitude greater than background s...

What happened to the crust under the High Lava Plains, Oregon?
A MEDLEY OF TECTONICALLY DRIVEN MAGMATISM IN THE NORTHWESTERN UNITED STATES I ORAL
volcanology, geochemistry and petrology | 13 december 2021
Anita Grunder
Thin crust, 30-35 km thick, underlies the High Lava Plains (HLP) of southeastern Oregon. Subcontinental lithospheric mantle is minor or absent based o...

Thermal Evolution of the 3 Ma to 0.1 Ma Goat Rocks Volcanic Complex, Washington Cascades
A MEDLEY OF TECTONICALLY DRIVEN MAGMATISM IN THE NORTHWESTERN UNITED STATES I ORAL
volcanology, geochemistry and petrology | 13 december 2021
Kellie T. Wall, Anita Grunder
We explore here the thermal evolution of the intermediate to felsic Goat Rocks Volcanic Complex in the southern Washington Cascade Range. This volcani...

Changes in andesite-dacite genesis over the 3-Myr lifespan of the Goat Rocks volcanic complex, central Cascade arc
THE MANIFESTATION OF SUBDUCTION: GEOCHEMICAL, PETROLOGICAL, AND GEOPHYSICAL CONSTRAINTS ON LITHOSPHERIC STRUCTURE, COMPOSITION, AND EVOLUTION II POSTERS
tectonophysics | 10 december 2019
Kellie T. Wall, Anita Grunder
At the Goat Rocks volcanic complex in the central Cascade arc, ~3 million years of andesite-dacite magmatism exemplify the temporal variability of eru...
