Geology of the Delphine Creek area, southeastern British Columbia: implications for the proterozoic and paleozoic development of the cordilleran divergent margin

Abstract

Strati graphic and structural relationships within, and adjacent to, the Delphine Creek area of southeastern British Columbia are consistent with the hypothesis that the Cordilleran divergent margin formed at the western edge of North America following rifting during the Late Proterozoic and continental separation at the approximate start of the Paleozoic (e.g. Stewart, 1972, 1976; Bond and Kominz, 1983). Within the study area, there is evidence for extensional faulting during deposition of the Middle Proterozoic Dutch Creek Formation
