  • ⁴⁰Ar/³⁹Ar Ages and Trace Element Variations in Colombian Emeralds

    Creator:
    Svadlenak, Ellen
    Abstract:
    The Colombian emerald deposits are globally unique because they are hosted in hydrothermally altered black shales on either side of the Cordillera Oriental. We used electron microprobe analysis to study variations in trace element concentrations in transects across emeralds, and used the ⁴⁰Ar/³⁹Ar dating method to determine the age of...
