ABSTRACT

Transcurrent faults and associated compressional structures affecting post-Middle Devonian rocks are recognized for the first time in the southern Gaspe Peninsula (Quebec). This region was previously thought to have experienced only minor normal fault readjustments after the Middle Devonian Acadian Orogeny. Four SW-striking fault systems with post-Acadian sinistral motion that have been identified along the north shore of Chaleur Bay are described here. These faults are kinematically compatible with large NW-striking dextral faults in eastern Gaspe, and suggest that ...
