... cores, they will provide the cores with independently dated time horizons. More than 12 40 Ar/ 39 Ar-dated tephra layers, exposed in bare ice on the summit ice cap of Mount Moulton, 30 km from their inferred source at Mount Berlin, range in age from 492 to 15 ka. These englacial tephra layers provide...
