Schematic cross-sections at the latitude of Volcanic Creek at four different time intervals, illustrating the exhumation of the Grand Forks complex (GFC), driven by Late Cretaceous orogenesis, followed by Paleocene to Eocene crustal extension. The evolution of three rocks (one in the footwall, two in the hanging wall to the Granby and Kettle River faults) is represented by the three different symbols. Plutonic rocks are ignored for simplicity. The east-dipping Kettle River fault is slightly older than the Granby fault, as the Coryell suite intrudes the Kettle River fault, but is cut by the Granby fault (Fig. 1).

Simplified composite cross sections (W–E) showing alternative models of the architecture between 49°N and 50.5°N, compiled from observations throughout the Shuswap metamorphic complex. Major gneiss domains are in italics: Ok—Okanagan, K-GF—Kettle–Grand Forks. Major faults and shear zones include: OVsz—Okanagan Valley shear zone, GF—Granby fault, KF—Kettle River fault, VSZ—Valkyr shear zone, SLF—Slocan Lake fault. T—Toroda Creek graben. (A) Depiction of the current understanding of gneiss domes and their bounding detachments and high-angle normal faults (e.g., Carr et al., 1987; Parrish et al., 1988; Simony and Carr, 1997; Cubley and Pattison, 2012). Note that the Valkyr shear zone is an E-throwing detachment, even though it dips to the west (Carr et al., 1987), because it is interpreted to be arched over the Valhalla dome and offset by the E-dipping Slocan Lake fault (see text for details). Also note that the downdip extensions of the Slocan Lake fault and Okanagan Valley shear zone have been identified at depth by seismic surveys but that the Granby and Kettle River faults, the Valkyr shear zone, and the faults bounding the Toroda Creek graben have not (Carr, 1995). (B) Depiction of how upper-plate reentrants (corrugations) potentially link the Okanagan Valley shear zone with the Kettle–Grand Forks and Valhalla gneiss domes. In this scenario, the Granby fault is a brittle W-directed overprint on the Okanagan Valley shear zone at the eastern termination of the Osoyoos-Greenwood reentrant. The Valkyr shear zone marks the eastern limit of the Okanagan Valley shear zone at the eastern termination of the Vernon-Fauquier reentrant. The alternative model proposed agrees with the Lithoprobe seismic data (Carr, 1995), where the Okanagan Valley shear zone is observed to be near horizontal between high-angle normal faults in the upper crust.
