iMAGE-CREATE 2021 Field School Southern Superior Craton (GEO5193C)
August 2nd – August 11, 2021
Instructors: Mark Hannington, David Diekrup, Alan Baxter, Marc Fassbender
Localities: Rouyn-Noranda/Timmins/Kirkland Lake/Temagami/Cobalt, Ontario/Quebec
Objectives
This 3 cr. graduate-level field course explores the assemblage architecture and geological history of the southern margin of the Superior craton. The course will follow a 1000-km traverse of the craton margin, crossing the Archean volcanic arc-like assemblages of the Noranda-Bousquet-Val d’Or corridor, oceanic rifts of the Kidd-Munro assemblage, collisional zones and successor basins of the Timmins-Porcupine district, post-collisional alkaline magmatic and sedimentary rocks of Kirkland Lake and Temiskaming, and Proterozoic rifting of the craton margin in the Cobalt embayment. The transect also covers some of the most important mineral deposits of Canada, including Archean komatiite-hosted nickel and volcanic-hosted massive sulfides and some of the world’s most important orogenic lode gold deposits in the Abitibi Greenstone Belt − the geology that launched a Century of Mining.
