BLACK ROCK DESERT, UTAH
Bimodal volcanism occurred in south-central Utah over the last 2.5 million years. This project examines chemical, temporal, and spatial relationships of basalt and rhyolite lavas within the Twin Peaks and Beaver Ridge subfields. Here, we will use the 40Ar/39Ar dating technique to determine precise eruption ages for the different volcanic events. We will use the chemistry of the rocks to model assimilation and crystallization process that would allow for the production of multiple lavas from the same magma chamber over geologic time. Finally, we will use zircon to estimate the temperature of the magma during crystallization prior to eruption, as a proxy for chemical evolution, and to date the timing of crystallization using the U/Pb dating technique.
Hosted at Westminster College in Salt Lake City, this project collaborates with researchers at the University of Wisconsin-Madison and Boise State University. As a primarily undergraduate institution, students at Westminster College will gain hands-on research experience that will allow them to acquire skills necessary for the workforce or graduate school.
