Abstract

During Tertiary time, two major episodes of igneous activity occurred in the Chignik and Sutwik Island quadrangles of Alaska. Leuco-basaltic to dacitic volcanism and granodioritic plutonism occurred during Eocene to Early Oligocene time, whereas leuco-basaltic to dacitic volcanism and quartz dioritic to granodioritic plutonism occurred from Late Miocene to Holocene time.
