Experimental Investigation of Rates and Mechanisms of Isotope Exchange (O,H) Between Volcanic Ash and Isotopically-Labeled Water

Nolan, Gary (University of Oregon, 2012)

The hydrogen and oxygen isotope ratios in hydrous minerals and volcanic glass are used as paleo-proxies to infer isotopic values of meteoric waters and thus paleo-climate conditions. Long-term exposure experiments with Mt ...
Experimental Investigation of Rates and Mechanisms of Isotope Exchange (O,H) Between Volcanic Ash and Isotopically-Labeled Water

Nolan, Gary (University of Oregon, 2012)

The hydrogen and oxygen isotope ratios in hydrous minerals and volcanic glass are used as paleo-proxies to infer isotopic values of meteoric waters and thus paleo-climate conditions. Long-term exposure experiments with Mt ...
H and O Isotope Systematics in Volcanic Glass: Hydration Experiments and their Application to Volcanic and Hydrothermal Processes

Hudak, Michael (University of Oregon, 2021-11-23)

The goal of my dissertation is to expand the application of H2O, δD, and δ18O in silicic volcanic glass to a greater diversity of pyroclast cooling, degassing, and rehydration histories. All pyroclasts must cool from ...
An Isotopic, Trace Element, and Volatile Investigation of Large-Volume Rhyolite Generation at the Picabo Volcanic Field of the Yellowstone Hotspot Track

Drew, Dana (University of Oregon, 2014-06-17)

Rhyolites of the Picabo volcanic field (10.4-6.6 Ma) of the Yellowstone hotspot in eastern Idaho are preserved as thick ignimbrites and lavas along the margins of the Snake River Plain. This study presents new O and Hf ...
Oxygen and hydrogen investigation of volcanic rocks: Petrogenesis to paleoclimate

Seligman, Angela (University of Oregon, 2016-10-27)

Knowledge of the isotopic evolution of volcanic eruptions is essential to volcanologists, geochemists, and paleoclimatologists. I isotopically evaluate the evolution of magmas from their initial formation, to eruption, and ...
Triple Oxygen Isotope in High-Temperature Hydrothermally Altered Rocks: A Record of Paleoclimate and Ancient Hydrosphere-Rock Interactions

Zakharov, David (University of Oregon, 2020-02-27)

In this dissertation, I use isotopes of H, O and Sr to trace interaction between meteoric waters, seawater and rocks in modern and extinct areas of high-temperature hydrothermal alteration. The ancient hydrothermal systems ...
Understanding the Origins of Yellowstone Hot Spot Magmas Through Isotope Geochemistry, High-Precision Geochronology, and Magmatic-Thermomechanical Computer Modeling

Colon, Dylan (University of Oregon, 2018-09-06)

The last several years have seen renewed interest in the origin of silicic magmas thanks to the developments of new microanalytical techniques allowing the measurement of the isotopic and trace element compositions of ...
