Reconsideration of the age of blueschist facies metamorphism on the Seward Peninsula, Alaska, based on phengite 40 Ar/ 39 Ar results
Abstract 40 Ar/ 39 Ar step‐heating and single‐grain laser fusion ages from phengites from the polydeformed and polymetamorphosed blueschist‐greenschist facies Nome Group fall into two groups.
