Applying U-Th Disequilibrium to Dating Siliceous Sinter
Continental hydrothermal systems are critical avenues for the crustal transport of heat and mass captured for geothermal energy and mineral exploration. Thus, understanding their temporal evolution and longevity is important for resource characterization. In particular, high temperature reservoirs …

Tufa-based reconstructions of Huasco Basin Lake levels
This thesis investigates the Salar del Huasco (northern Chile) as a potential site for palaeohydrological reconstructions of precipitation over the South American Altiplano, and presents a preliminary lake level chronology for the last deglaciation. Resolving the timings of past lake level …

Zircon crystallization patterns from U-Th dates inform U-Pb estimates of volcanic eruption ages
… on events from 4.5 Ga to < 1Ma by measuring the timing of zircon crystallization. Absolute uncertainties on U-Pb zircon dates are significant enough to obscure zircon crystallization and complicate estimating the relationship between zircon crystallization and volcanic eruption. We use …
