Tectonic burial, thrust emplacement, and extensional exhumation of the Cabot nappe in the Appalachian hinterland of Cape Breton Island, Canada
Article Abstract:
The deformations in the Appalachian hinterland of Cape Breton Island, Canada, are characterized by thrusting events, metamorphic nappe emplacement, and extensional denudation during the Devonian-Carboniferous era. Thrusting events in Cape Breton Island during the Silurian era produced tectonic burial and metamorphism. Thrusting during the Devonian era produced the Cabot nappe over the greenschist-grade footwall rocks. The final exhumation of the nappe from the greenschist crustal region to the surface occurred during the Late Devonian era.

Comment on "Tectonic burial, thrust emplacement, and extensional exhumation of the Cabot nappe in the Appalachian hinterland of Cape Brenton Island, Canada" by Gregory Lynch
Article Abstract:
The interpretation of the tectonic burial, thrust emplacement and extensional exhumation of the Cabot nappe in the Appalachian hinterland of Cape Breton Island, Canada, is dependent only on generalizations. Furthermore, these interpretation create predictions that do not match present geological database. Geologic information on the region, however, do not support the idea that rocks of the Cabot nappe is part of a contiguous nappe.

Article Abstract:
Cabot nappe is a well-defined feature that contrasts with rocks which are adjacent to and outside the area. This disproves the idea that rocks in Cabot nape are part of a contiguous nappe. Furthermore, the area is geologically interesting since it reveals the process of Transport of high-grade rocks during exhumation. The position of the rocks also defines the limits of the nappe.
