(A) Regional compilation map showing extrapolation of the detachment zone throughout the Ottawa River Gneiss Complex (ORGC) using mega-cross-folds as a proxy. More than 60% of the exposed ORGC consists of the detachment zone; the two areas of metamorphic core are termed Algonquin (A; which includes smaller Rosseau and Go Home subdomains) and Dozois (D). Base-map from Davidson (1984) and Rivers et al. 2012; (interpretation supersedes that of Rivers et al. (2012) in which the Algonquin and Lac Dumoine domains were correlated). (B) Orogen-normal seismic section across the northeastern corner of map (approximate location, continuing beyond map limit, shown by dotted line). Bsz—Bancroft shear zone, CABbz—Composite Arc Belt boundary zone, Csz—Cadgecrib shear zone, GF—Grenville Front, GFTZ—Grenville Front Tectonic Zone, RC—Réservoir Cabonga domain, and SCLM—subcontinental lithospheric mantle.

(A) Information compiled from publications of the Ontario Geological Survey and the Ministère des Richesses Naturelles du Québec, and from Montreuil and Constantin (2010) and Lambert et al. (2023) in vicinity of the Baskatong Promontory. (B) Reinterpreted from Martignole et al. (2000). Two locations of the Allochthon Boundary (AB) are shown, after Ketchum and Davidson (2000; K&D2000) and Herrell et al. (2006; HDM2006); see text for discussion. Km-scale cross-folds in southeast of map that affect the base of the cover are from Lumbers (1982) and Easton (2001). L > S fabrics parallel to hinge lines of m-scale cross-folds near the Ottawa River and Barry’s Bay are our data.
