Includes bibliographical references. "Devonian plutonic suites in the Canadian Appalachians are locally associated with Sn, W, Mo and In mineralization. In central Newfoundland, some of the most mineralogically-prospective plutons, for example the Ackley granite, are spatially associated with the Gander/Avalon terrane boundary. This relationship suggests that there may be tectonic and/or structural controls on pluton emplacement and localization of mineralization. The Geological Survey of Canada Targeted Geoscience Initiatives IV Intrusion-Related Mineralization Project is focused on the tectonic controls on porphyry-style mineral systems to determine their potential as a vector towards zones of high mineral prospectivity. Identifying such relationships is especially significant in regions like the Canadian Appalachians where extensive glacial cover often masks direct observations of mineralization. Herein, we present preliminary results from our SHRIMP U-Pb and ⁴⁰Ar/³⁹Ar single crystal and in situ geochronological and thermochronological study. These data are used to constrain the timing of deformation along the Dover Fault, which marks the Gander-Avalon terrane boundary, and the regional emplacement/cooling history of spatially-associated plutonic suites. The role of shear zones as pathways for magmas and ore and implications for tectonics and mineral potential of the region are under consideration. …"--Introduction.
