Full Title: Tectonic, Plutonic, and Metamorphic History of the Central Kootenay Arc, British Columbia, Canada
Author: Percy Crosby
From the original catalog copy: The Kootenay arc is a major structural element in southeastern British Columbia and northeastern Washington. Its central part, mapped here, spans central Kootenay Lake and includes a metasedimentary and metavolcanic section thicker than 20,000 feet and ranging in age from Proterozoic to Triassic. The interdependence of rock deformation, metamorphic recrystallization, and igneous intrusion in the light of absolute age determinations is of crucial significance and suggests a far more complex chronology than once postulated on geologic evidence alone.
