Devonian extension in Northwestern Newfoundland: Ar-40/Ar-39 and U-Pb data from the Ming's Bight area, Baie Verte Peninsula
The Ming's Bight Group of northwestern Newfoundland, an outlier of Humber Zone continental margin rocks, is entirely surrounded by ophiolitic rocks of the Dunnage Zone. Structures in the Ming's Bight Group and adjacent ...
Last Gasp of the Grenville Orogeny - Thermochronology of the Grenville Front Tectonic Zone Near Killarney, Ontario
We present U-Pb (titanite, zircon) and Ar-40/Ar-39 (hornblende, mica, K-feldspar) data from a transect across the western part of the Grenville Front Tectonic Zone (GFTZ) near Killarney, Ontario. High-grade metamorphic ...
Evolution of orogenic wedges and continental plateaux: insights from crustal thermal-mechanical models overlying subducting mantle lithosphere
The links between an early phase of orogenesis, when orogens are commonly wedge shaped, and a later phase, with a plateau geometry, are investigated using coupled thermal-mechanical models with uniform velocity subduction ...
