  • New Insights into Mantle Dynamics from Helium Isotopes and Argon Geochronology

    Creator:
    Konrad, Kevin
    Abstract:
    Earth’s mantle extends to nearly 3000 km depth, comprises >80 % of Earth’s total volume, and has the largest influence on the primordial and radiogenic heat budget. Despite its importance, the structure and composition of the mantle is still debated. There are three primary models for Earth’s mantle structure that...

  • Geochemical and helium isotopic variability within the Lau Basin

    Creator:
    Goddard, Charlotte Ives
    Abstract:
    This research incorporates geochemical and helium isotopic analyses of Lau Basin volcanic glasses, along with helium isotopic analyses of water column hydrothermal plumes to better understand the processes that control the formation and evolution of this backarc basin. Lavas newly collected from the four southernmost segments of the Valu Fa...
