AbstractThe Slave River, Peace River and Lake Athabasca map-areas include the Precambrian Shield to the northeast (not compiled in this publication) and its Phanerozoic cover to the southwest. The Shield surface dips gently southwest but has been pervasively faulted, predominantly along northeast trends, and gently warped. The major faults (Great Slave Lake Shear Zone, Virgin River Shear Zone/Snowbird Tectonic Zone, Tathlina, Rabbit Lake, Trout Lake, Boundary Lake, and Dunvegan fault zones) and uplifts (Tathlina, Peace River, and Athabasca arches) were reactivated at various times during deposition of the cover with pronounced effects upon facies and environment. Paleozoic platformal clastic and carbonate strata were deposited initially during Early Cambrian to Late Ordovician time but are preserved at the surface only northwest of Great Slave Lake. These were overlain unconformably by a succession of clastic, carbonate and evaporitic strata from the Late Silurian to the Jurassic. Complex facies relationships resulted from sea level changes and the development of a pronounced barrier reef at Pine Point and to the west in the subsurface during the Middle Devonian. Major reef development and accompanying dolomitization and Pb/Zn mineralization appears to be spatially associated with reactivated basement fault zones. During the Cretaceous, orogenic events west of the map-area resulted in uplift and erosion of the Paleozoic platform and unconformable deposition of an easterly-prograding clastic wedge. Some dolomite diagenesis and mineralization of the Devonian barrier reef may have occurred at this time. Numerous Late Cretaceous diatremes intruded the section in the Buffalo Head Hills and Birch Mountains regions. Two meteorite impact craters (Steen River Astrobleme and Hotchkiss crater) deform Paleozoic and possibly Mesozoic strata.
