The Sanak-Baranof belt (SBB) extends for over 2,000 km along the southern Alaskan coastline and the plutons systematically young from 63 Ma in the west to 47 Ma in the east. On Yakobi and Chichagof Islands in Southeast Alaska, these plutons intrude the Sitka Graywacke that is correlated with the Lat...
