Dr. Jason Kaiser’s fascination with volcanoes has taken him all over the world in order to understand how and why magma accumulates in the Earth’s crust. As an assistant professor of geology at Southern Utah University, Dr. Kaiser uses his experience and global research to influence and enrich his classroom.
In order to learn about different geological features, Kaiser has travelled to Bolivia, Chile, Argentina, Iceland, the Bahamas and across the United States. He is currently investigating geothermal energy sources and potential disasters in southern Utah, as one of his broader interests include geologic hazards and natural disasters.
He earned a bachelor’s degree in geology from the Missouri University of Science and Technology, a master’s degree in geology from the University of Massachusetts-Amherst, and a Ph. D. in Volcanology from Oregon State University. His dissertation was on the volcanology, stratigraphy, and geochemistry of the Pastos Grandes Caldera Complex in Southwest Bolivia.

What I'm Reading: ‘Disrupting Ourselves’
The Chronicle of Higher Education online
Randall Bass, vice provost for education and a scholar of teaching and learning at Georgetown University, presented some of his thoughts on learning and higher education as part of our convocation series at Southern Utah University. Afterward, I was inspired to read more from him. In his article "Disrupting Ourselves: The Problem of Learning in Higher Education," published in Educause Review, Mr. Bass discusses how new ideas are reframing what we think of as the "formal curriculum" and how to redesign courses to have a better impact on learning. This got me thinking about how we are incorporating high-impact practices into our curriculum.

Climate and Crowding Pressures Show that Bryce Canyon’s Future isn’t Set in StoneKUER
Ciara Hulet, Jason Kaiser
In its century of existence, the landscape of Bryce Canyon National Park has changed, just as it has for millions of years. But with climate change and increased visitation, those geological processes are under threat, potentially changing people’s relationship with the land.
Million-year melt–presence in monotonous intermediate magma for a volcanic–plutonic assemblage in the Central Andes: Contrasting histories of crystal-rich and crystal-poor super-sized silicic magmasEarth and Planetary Science Letters
Jason F. Kaiser, Shanaka de Silva, Axel K. Schmitt, Rita Economos, Mayel Sunagua
2017 The melt–present lifetime of super-sized monotonous intermediate magmas that feed supereruptions and end life as granodioritic plutons is investigated using zircon chronochemistry. These data add to the ongoing discussion on magma assembly rates and have implications for how continental batholiths are built.
Geospatial and Petrographic Analysis of Leucogranite in the Beaver Dam Mountains, Southwest UtahThe Geological Society of America
2016 The presence of leucogranite outcrops in the Western United States suggest possible locations of suture zones for Precambrian terranes accreted to Laurentia. While large scale maps exist, little has been done to extend the suture zones at a fine scale, between Proterozoic terranes such as the Mojave and Yavapai Provinces. Outcrops of Proterozoic leucogranite in the Beaver Dam Mountains of Southwest Utah and the Virgin Mountains of Northwest Arizona indicate possible locations of these suture zones. Using GIS and GPS equipment the locations of leucogranite outcrops following a North-South trend, up to one kilometer in length have been identified near the Utah/Arizona/Nevada border. After field verification these rocks have been correlated to Precambrian basement rocks such as the Grand Canyon Metamorphic Suite to the southeast.
Field and Petrographic Analysis of the Indian PeakCaliente Caldera Complex at Condor and English Canyons in Eastern NevadaThe Compass: Earth Science Journal of Sigma Gamma Epsilon
2016 The Indian Peak-Caliente Caldera Complex, or IPCCC, is an ideal site to study how large-scale tectonic forces can influence mineralogy on a local scale. This research was completed and compiled by the Tectonics and Mineralogy classes at Southern Utah University during a joint class field study and subsequent laboratory analyses. During the field trip, the main focuses were to observe caldera collapse relationships and ignimbrite features and to collect samples at Condor Canyon and English Canyon, two sites near the border between Nevada and Utah within the IPCCC. After the field trip, the Tectonics class completed a detailed literature review of the overall tectonic evolution of the region while the Mineralogy students petrographically analyzed the collected samples. This report provides a summary of the results, including mineralogical descriptions; an interpretation of a piece-meal, or piston-like, collapse of the caldera complex; and a connection between the local geology and the regional tectonic setting.

The Pastos Grandes Caldera Complex of SW Bolivia: The building of a composite upper crustal batholithAmerican Geophysical Union
2011 The Pastos Grandes Caldera Complex in SW Bolivia is one of the longest-lived in the Altiplano Puna Volcanic Complex (APVC) of SW Bolivia. This nested caldera complex has erupted over 2500 km3 of ignimbrite from at least two caldera-forming supereruptions and an ignimbrite shield depositing the 5.45±0.02 Ma Chuhuilla, the 5.22±0.02 Ma Alota, and the 2.89 ± 0.01 Ma Pastos Grandes Ignimbrites. Late stage lava domes of the Chascon Runtu-Jarita complex in the southwest of the caldera represent the most recent volcanic activity (~85 ka). Each eruption represents a discrete pulse of magma injected into the shallow crust beneath the complex mapping out the incremental construction of a large upper crustal batholith.
