Their geometry resembles a ramp-and-flat style of deformation that results in a thin upper plate above the 10-12 km (about 4.0 s) detachment. Northwest-southeast horizontal shortening is estimated to be at least 55 km. This large amount of shortening implies that much of the Superior province was detached during the formation of the Kapuskasing structural zone. This content is PDF only.
