Thermochronology & Geochronology
Dept of Geological Sciences, University of Colorado Boulder
We use thermochronology, geochronology, and geologic observations to address problems in continental tectonics and mantle dynamics. Over the last decade, we have particularly focused on applying “deep-time” (U-Th)/He thermochronology to better understand the coupling of deeper Earth and surface processes over extended (10s-100s Ma) timescales. We also emphasize the development and refinement of both conventional (e.g., apatite, zircon) and novel (e.g., conodonts, perovskite, rutile) (U-Th)/He thermochronometers. We especially seek creative, collaborative applications of (U-Th)/He data to problems in fields in which the technique has not typically been used (e.g., to constrain lunar impact histories, calibrate mantle dynamic models, date kimberlite emplacement). Recent study areas include the southern African Plateau, the Marlborough Fault System of New Zealand, the Rocky Mountains, the U.S. midcontinent, and the Canadian shield.
Our (U-Th)/He lab is the core facility of our research group. I established this facility in 2012 with support from an NSF Instrumentation & Facilities award. Please visit our lab website and contact me or lab manager Dr. Jim Metcalf if you’re interested in obtaining data in our lab.
Our group fosters a collaborative and supportive environment in which we emphasize high-quality data, careful thinking, and clear writing. Our goal is to consistently be open-minded to new ways of thinking about the interpretation and significance of our results. We are always seeking smart, creative, motivated students who are a good fit for our research team.
