(Humber zone) comprises foreland-propagating, northwest-directed thrust faulting, nappe
emplacement, and regional prograde metamorphism in response to the obduction of large
ophiolitic nappes during the Taconian orogeny. In the internal Humber zone, this event is
dated at 462±3 Ma (late Middle Ordovician), which is interpreted to represent the timing of
near-peak Taconian metamorphism. Superimposed hinterland-directed structures are …
