AbstractSubsurface mapping indicates that the region northwest of the Great Slave Shear Zone contains an array of previously identified northeast-trending faults and fault zones that cross abrupt inflections of contours on structure and isopach maps. The Tathlina Fault Zone, the Rabbit Lake Fault Zone, and the Cameron Hills Structure (formerly "Hay River Fault Zone") are all large, northeast-trending fault arrays
that lie northwest of the shear zone. Southeast of the shear zone, contours on subsurface structure maps display fewer pronounced inflections, and inferred faults are fewer in number except in the Peace River Arch area. A new feature defined in this study, the Enterprise Structure, extends northeast near and subparallel to Hay River.
Aeromagnetic and seismic data demonstrate the presence of subvertical faults, and a large, well-defined magnetic "low" extends about 70 km northwest from the Great Slave Shear Zone at the west end of Buffalo Lake.
