Latest Proterozoic to early Cambrian sedimentary-tectonic evolution of a passive margin sequence, northeastern Washington
The late Proterozoic to Early Cambrian Three Sisters formation, Addy Quartzite, and Gypsy Quartzite lie near the base of the Cordilleran miogeocline in northeastern Washington. Detailed stratigraphic and sedimentary examination of these units extends understanding of the evolution of western North America. These units were deposited on a newly rifted passive margin and record the final stages of late Proterozoic rifting and the early stages of subsequent early Paleozoic subsidence and transgression. The three Sisters formation, Addy Quartzite, and Gypsy Quartzite are correlative with the Brigham Group in southeastern Idaho and Utah, the Gold Creek Quartzite in northern Idaho, and the Flathead Quartzite in Montana and Wyoming.
