The Bonne Bay cross-strike discontinuity of western Newfoundland corresponds with major along-strike changes in depositional facies and structural styles of rock units overlying Grenville basement. Facies associations in time-equivalent Lower Ordovician rock units of the Humber Arm Allochthon change abruptly in character at Bonne Bay. The Bonne Bay cross-strike discontinuity is inferred to represent a transfer fault formed during continental rifting at the inception of the Appalachian cycle that was reactivated during the subsequent history of the orogen. -from Authors
