Along-strike Propagation of Slab Breakoff At The End of The Taconic Orogeny: A Model of Shortening-extension Transition Accompanying Strike-slip Faulting

Basic Information
Author: LIM, Chul and KIDD, William S.F.
Description:Orogen-parallel normal faults and veins recently recognized within the Taconic frontal zone in eastern New York followed thrust convergence during the last part of the Ordovician Taconic orogeny. Mapping in the Bald Mountain region of the frontal zone identifies major normal faults truncating shortening structures and continuing to the north and south. Correlation with normal faults showing the same cross-cutting relationships such as the Mettawee Fault to the north in western Vermont and the high-angle normal faults in the areas near Troy and Hudson to the south in eastern New York suggests that the present western boundary of the Taconic Allochthon is marked by an approximately 200 km long, east-side-down normal fault system.
