Abstract:

A correlation chart showing the evolution of the Manitoba–Saskatchewan segment of the Paleoproterozoic Trans-Hudson Orogen (THO) has been constructed based on available geochronological and isotopic data. Geological, petrological, geochemical, and structural data have also been incorporated into the correlation chart to provide finer detail and to allow comparison of specific tectonic events. The chart also emphasizes that the bounding Archean cratons (Superior, Hearne, Sask) have been significantly affected by Paleoproterozoic events, and it is hoped that this chart will also facilitate comparison with other Paleoproterozoic orogens in North America and beyond.

Un diagramme de corrélation montrant l'évolution du segment Manitoba–Saskatchewan de l'orogène trans-hudsonien ( « THO », Paléoprotérozoïque) a été construit en se basant sur les données géochronologiques et isotopiques disponibles. Des données géologiques, pétrologiques, géochimiques et structurelles ont aussi été incorporées dans ce diagramme de corrélation pour fournir plus de détails et pour permettre de comparer des événements tectoniques spécifiques. Le diagramme souligne également que les cratons archéens limitrophes (Supérieur, Hearne et Sask) ont été grandement touchés par les événements paléoprotérozoïques; nous espérons que ce diagramme facilitera aussi les comparaisons avec d'autres orogènes Paléoprotérozoïques en Amérique du Nord
