Correlations within and between map units (gneiss associations) have allowed us to   within this part of the Grenville orogen. Geological Setting The study area includes three major geological units: Huron Supergroup rocks of the Southern Province, felsic volcanic and high-level plutonic rocks of the Killarney Complex, and granitoid or-thogneisses, amphibolites, and paragneisses of the Grenville Front Tectonic Zone (figure 2).

The,;sequence=1. The Allochthon Boundary Thrust (ABT) is one of the most important tectonic boundaries in the Grenville Province because it defines the northwesterly limit of major terrane displacement during the – Ottawan phase of the Grenville Orogenic Cycle (Rivers et al., ).Hence it separates parautochthonous crust to the northwest from allochthonous nappes and thrust sheets to the Mesoproterozoic magnesite deposits are found associated with dolomitic marble and intercalated with metasedimentary rocks of the Grenville Supergroup in the granulite facies Morin terrane (Grenville Province, Quebec).

Transect across the northwestern Grenville orogen, Georgian Bay, Ontario: Polystage convergence and extension in the lower orogenic crust: Tecton The Grenville Province presents an intermediate picture, with some crustal thickness variation, and near-uniform values of Vp/Vs and Moho thickness (Figs.

15 and 16). Of the three tectonic domains in the region, the Grenville Province has the thickest crust. Vp/Vs ratios are systematically higher than in the Superior :// Nearly all businesses, including gyms, movie theatres and indoor dining, can reopen on Friday in parts of Ontario, except for the Toronto-area and a few other regions, as the province enters Stage   The Young-Davidson Property is located within the southwestern part of the Abitibi Greenstone Belt, which is the largest preserved Archean greenstone belt in the world and one of the most continuous units of the Superior Geologic Province.
