Surv., Paper B, p. – Google Scholar Beyond North America, the Grenville Province has been recognized inside exhumed anticlinal inliers in the Caledonia of Northern Ireland, Scotland, and then in Norway and the Sveconorwegian Province in Scandinavia (Davidson, ; Lorenz et al., ).According to several authors, it would continue from Central America to Antarctica, and from India to Australia (e.g.

[A Davidson; R M Easton] The Grenville orogenic cycle, between ∼ and Ma, involved accretion of magmatic arcs and/or continental terranes to the Laurentian craton.

83–1B, An alternative position for this terrane boundary is the Black Lake Shear Zone (BLSZ), which is interpreted to separate the Frontenac Terrane from the Adirondack Lowlands Terrane in the southwestern Grenville Province ().The presence of the BLSZ has previously been interpreted based on changes in the lithologic (Davidson, ) and isotopic character (Peck et al., ) between the two Systematic mapping of a transect along the well‐exposed shores of Georgian Bay, Ontario, combined with the preliminary results of structural analysis, geochronology and metamorphic petrology, places some constraints on the geological setting of high‐grade metamorphism in this part of the Central Gneiss Belt.
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).

The 39 papers in this volume offer a system-wide perspective on rocks and processes of the Mesoproterozoic Grenville orogen and Appalachian inliers and include many The Grenville Province is separated from older units such as the Superior and Southern provinces, the Killarney Magmatic Belt, the Eastern Granite-Rhyolite province and the Midcontinent Rift by the Grenville Front (GF; Williams et al).
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.

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.
