Langdon and Hall (1994) interpreted the tectonic structure of the region to be a wrench system involving the major NE-trending faults with minor parallel and cross-cutting dextral fault arrays and shear zones (i.
One WNW-striking dextral fault plane with a similar fabric was also identified (Fig.

These faults are kinematically compatible with large NW-striking dextral faults in eastern Gaspe, and suggest that these structures reflect a widespread Alleghanian paleostress system that probably affected the entire Quebec Appalachians.
