Composite north–south cross sections of western Superior Province (modified from Percival et al. 2004), showing contrasting geometry and interpreted fault vergence north and south of the North Caribou superterrane (NCS). Segment A–B was based on Western Superior Lithoprobe line 1 seismic data (White et al. 2003). Segment C–D is schematic and speculative (see text for discussion). Note the similarity of a possible interpretation of geometry and kinematics around the Gods Lake Narrows shear zone (GLNSZ), and those around the Quetico fault (QF), and the Sydney Lake – St. Joseph fault (SLF), as schematically shown by the insets above the sections. Locations of sections are shown in Fig. 1. NSS, north Superior superterrane; OST, Oxford–Stull terrane; WR, Winnipeg River subprovince.

B: Schematic section along Lithoprobe seismic line WS-1 (White et al., 2003). SLF—Sydney Lake fault; QF—Quetico fault. C: Seismic data with interpretation, WS-1D and southern part of WS-1A. Numbers for equivalent features in panels C, D, E: 1—superstructure with upright (phase 1) structures; 2—high-strain zone (Abschwerungszone) decoupling superstructure from infrastructure; 3—ductile infrastructure with gently dipping (phase 3) structures, including lower-crustal nappes; 4—strong lower-crustal indentor. Fine dashed lines separate zones with contrasting reflectivity (C) and strain (E). D: Interpreted field relations in transition zone between Kapuskasing lower and upper crust (after Moser, 1994; Bursnall et al., 1994). E: Model 2 at ∼35 m.y.; similar to model 1 (box C, Fig. 1E, Table DR1 [see text footnote 1]) but with thinner lower crust (10 km), uppermost crust removed by postorogenic erosion, and faster convergence rate (2.5×) leading to indentor collision at 25 m.y.
