Text Description:
Sample of juvenile block from block-and-as flows deposited on the debris avalanche formed during flank collapse of ancestral Mt. Spurr (“pyroclastic fan”; sample PF-38 of Nye and Turner (1990)). From exposure in upper W wall of canyon just west of camp. Small (~1mm) equant plag + larger cpx. Abundant small irregular pore space. Abundant "well cooked" inclusions, some with lots of biotite (mafic schist inclusions?).

General Mineralogy Description:
Small (~1mm) equant plag + larger cpx. Abundant small irregular pore space. Abundant "well cooked" inclusions, some with lots of biotite (mafic schist inclusions?).
