AbstractP rince R upert (east half) and Skeena map- areas cross the Coast Mountains of British Columbia between latitudes 54 ° and 55 ° N , and about the Alaska Panhandle . They are underlain mainly by a northwest - trending zone of gneiss and migmatite that is flanked and penetrated by large bodies of plutonic rock. Sediments and volcanics in the western half of the area are of uncertain age, but are thought to be Late Palaeozoic or Early Mesozoic . They are regionally metamorphosed to gneisses and schists . Sediments in the eastern half are unmetamorphosed and are of Late Jurassic and Early Cretaceous age. The plutonic rocks, which constitute almost half the exposed rock in the area, mainly diorite, quartz diorite, granodiorite, and quartz monzonite, and are regarded as post-Early Cretaceous in age. They commonly grade into the Palaeozoic gneiss complex. Major faults probably underlie some of the pronounced northwest-trending channels. Several old prospects of gold , copper, silver, zinc, iron, limestone, and salt occur within the area .
