Abstract

The Kootenay Arc in Northeastern Washington and southeastern British Columbia contains the transition between autochthonous Upper Proterozoic to lower Paleozoic miogeoclinal strata and outboard Paleozoic to Mesozoic eugeoclinal terranes of uncertain paleogeographic affinity. To better understand the nature of this transition, U-Pb detrital zircon geochronologic studies were carried out on Upper Proterozoic and lower Paleozoic sedimentary units in the Kootenay Arc. -from Authors
