Schists of the central Alaska Range

TL;DRAbstract

The schist formations of the central Alaska Range lie in belts that trend east-west. The formations are deformed into a broad arch having steep limbs, and there is a belt of gentle dips in foliation along the north side of the arch. The Birch Creek Schist underlies a belt fr-10 miles wide along the axis of the arch and is flanked on the north by the Keevy Peak Formation, beyond which is the Totatlanika Schist. South of the Birch Creek Schist are metavolcanic rocks.
