Abstract
The Hudsonian Torngat Orogen in the North River map area, Labrador, evolved through 1) early thrusting and associated isoclinal folding in lower Proterozoic supracrustal cover rocks, and the development of a regional tectonic fabric at peak metamorphic grade; 2) folding and intense shearing on subvertical planes, characterized by a subhorizontal NNW-plunging extension lineation during sinistral transpression; and 3) E-directed thrusting during uplift of the orogen. These structures are interpreted as progressive features that resulted from E-W oblique collision of the Archean Nain and Rae continental blocks across a 160°-striking boundary. -Authors
