The tectonic evolution of the Chugach-Prince William Terrane (CPW), an accretionary complex along the southern Alaskan margin, has been the subject of much debate. There are two prevailing hypotheses for the location of the CPW at the time of its intrusion by the plutons of the Sanak-Baranof belt, and both require distinctly different source regions for the sediment of the CPW flysch. Therefore, a better understanding of the provenance of these sediments will help constrain the location of the CPW at the time of the deposition of its sediments. This study presents an analysis of new U/Pb detrital zircon, mineralogical …
