Résumé
The 2023 CTG Fall workshop will be held in the Grenville Province, a Mesoproterozoic to early Neoproterozoic orogenic belt that covers an extensive area north of the St. Lawrence River from Lake Ontario to Labrador. The Grenville Province is mostly composed of amphibolite to granulite facies metamorphic rocks and provides a window into the structural styles of deformation at various levels in the continental crust. The field trip will take place around Lac Bouchette, south of Lac St. Jean, an area that has been mapped by the Ministère des Ressources naturelles et des Forêts du Québec in 2018 (Moukhsil and Daoudene, 2019a). The area exposes 1520-990 Ma orthogneiss, metasedimentary units and intrusive magmatic suites. Several phases of deformation affected the area, ranging from mid-crustal folding and shearing to upper-crustal brittle faulting. The field trip will provide an overview of the local geology, with a strong focus on the Saint-François-de-Sales Shear Zone (Moukhsil and Daoudene, 2019b), a prominent structure that marks a transition from exhumation to strike-slip and/or thrust tectonics at the end of the Ottawan phase of the Grenvillian orogeny. The group will convene at Auberge Eva, in Lac Bouchette, on the evening of Friday October 20. The field trip will run on Saturday and Sunday October 21-22. Posters will be presented on Saturday evening.
