Article
The vorticity axis of deformation within a shear zone is a rotational axis controlled by the relative movement of its boundaries. When characterized, it is a reliable tool to determine the ductile flow geometry (monoclinic general, monoclinic transpressive, or triclinic) and an asset to identify the kinematics of complex oblique collisions. Advance...
Conference Paper
Full-text available
Devonian post-orogenic granitoids of the Canadian Appalachians are an important polymetallic metallotect that includes significant resources such as New Brunswick’s Sisson and Mount Pleasant deposits. Accretionary orogenic systems like the Canadian Appalachians tend to be protracted and involve multiple accretionary episodes. While post-orogenic gr...
Article
Canadian Malartic is a large-tonnage, low-grade Archean gold deposit (16.3 Moz, 1.08 g/t Au) located in the Abitibi region of Québec, Canada. A large part of the mineralization is hosted in the Pontiac Group metasedimentary rocks, which consist of mudstones to greywackes at upper greenschist to amphibolite facies. In exploration and production envi...
Technical Report
Full-text available
The Eastern Highlands shear zone (EHSZ), in the Cape Breton Island portion of Appalachian Orogen, records two ductile deformation events (D 1 and D 2) from Early Silurian to Late Devonian. The Devonian is a key period for the economic endowment of the orogen during which intrusion-related mineralization may be associated with active and/ or reactiv...
Article
The Pontiac Subprovince is located in the Superior Province, south of the Abitibi Subprovince. The metasedimentary rocks of the Pontiac Group are characterized by a Barrovian metamorphic gradient increasing from north to south from biotite- through garnet- to staurolite-zone conditions. The Pontiac Subprovince has been interpreted as an accretionar...
Article
Canadian Malartic, with a total endowment of 16.3 Moz Au, is an important example of a large-tonnage, low-grade Archean gold deposit (current reserves of 204 Mt @ 1.08 g/t Au). It is located in the southern Superior Province in contact with, and immediately south of the east-west trending Cadillac-Larder Lake fault zone, which delineates the bounda...
Technical Report
The Eastern Highlands shear zone (EHSZ) is located on Cape Breton Island where it separates rocks of the Bras-d’Or and Aspy terranes within Ganderia in the Appalachian accretionary belt. It records late Silurian to Early Devonian shear with east-over-west kinematics (D1) and a second deformation event (D2) with oblique dextral and west-overeast kin...
Technical Report
La Sous-province métasédimentaire de Pontiac est située au sud de la Sous-province de l’Abitibi, au sein de la Province archéenne du Supérieur. La juxtaposition des deux sousprovinces est généralement interprétée comme le résultat d’un processus de subduction. Ce contexte tectonique serait à première vue compatible avec un métamorphisme de type bar...
Article
The structural setting of the Pontiac Subprovince in the vicinity of the world-class Canadian Malartic gold deposit has been revisited by combining and reinterpreting airborne geophysical surveys together with a century of structural observations. Felsic-intermediate intrusive bodies are a key component of this deposit. Defining the regional and lo...
