Annual Graduate Student Research Award
The Geo-and Thermochronology Research group at the University of Calgary invites graduate students to submit proposals that require the use of geo-and thermochronology analyses to answer compelling research questions. The proposed work should be a well-designed experiment that answers a fundamental research question by using fission track dating, (U-Th)/He dating or laser ablation U-Pb dating on apatite or zircon. The proposed study can include the analysis of bedrock or detrital material using one or multiple dating techniques. Methodological research projects that aim to advance dating techniques and may include other mineral phases will also be considered.
The annual deadline for submitting the proposal is March 15. More information on the award, eligibility and proposal guide can be found here.
Emily Johns-Buss (Memorial University) Timing and Rates of Appalachian Basement Exhumation in Eastern Newfoundland The Newfoundland-Iberia magma-poor rift system developed during the protracted breakup of supercontinent Pangea and Mesozoic opening of the North Atlantic Ocean. Triassic to Jurassic stretching-thinning, Early to mid-Cretaceous mantle exhumation, and mid-Cretaceous breakup-related events define the phases of Newfoundland-Iberia rift evolution, however, the predicted exhumation histories of onshore basement domains during Mesozoic rift development have yet to be tested. This project will use zircon U-Pb, fission-track (ZFT) and (U-Th)/He (ZHe) dating of Appalachian basement rocks in eastern Newfoundland to investigate the timing, rates, and spatial patterns of bedrock exhumation along an archetypal magma-poor rift margin. The multimethod dating approach will characterize cooling histories of Appalachian intrusive rocks from ~750 °C to ~250 °C to ~180 °C and estimate exhumation rates through the respective temperature windows. Precambrian to Paleozoic intrusive rocks are predicted to yield younger, Mesozoic ZFT and ZHe ages and exhumation cooling histories that coincide with phases of Triassic to Cretaceous rift evolution. We will target spatially widespread basement rocks to test exhumation patterns predicted by magma-poor rift models, including possible margin-parallel trends and increased rates of exhumation during the Triassic to Early Jurassic and Late Jurassic to mid-Cretaceous.
