Abstract
Carbonate and siliciclastic sedimentary rocks of the latest Neoproterozoic Miette Group (Windermere Supergroup) and earliest Cambrian Gog Group near Jasper, Alberta, Canada provide a new record of ocean chemistry evolution at the Proterozoic-Phanerozoic transition. Correlated high resolution transects of stable isotope, 87Sr/86Sr, and elemental data are presented from the diachronous Yellowhead and Astoria platforms in the Rocky Mountains, and from basinal equivalents in the Cariboo Mountains.
