Mineral chemistry and thermometry of metamorphosed mafic rocks in the contact aureole of the Kiglapait intrusion
Includes bibliographical references. Includes illustrations. Mafic granulites surrounding the Kiglapait layered intrusion Labrador, were previously thought to represent a contaminated chilled margin (Outer Border Zone) of the intrusion. Mineral chemistry data combined with petrographic observations...
