Résumé(disponible en anglais seulement)
The Detour Lake gold mine and Lower Detour zones (e.g. Zone 58N and Zone 75) are located in the northwestern part of the Abitibi greenstone belt and are hosted in a volcanic sequence of the 2.73 to 2.72 Ga Deloro assemblage or in altered feldspar porphyry intrusive(s). Mineralization consists of low-grade disseminated quartz-sulphide zones and silicified high-grade zones, including laminated quartz-tourmaline-carbonate veins and stockworks. Ore zones are commonly oriented sub-parallel to a series of high-strain zones occurring co-planar and in the hanging wall to the regional-scale Sunday Lake and Lower Detour deformation zones. The latter zone has a close spatial relationship with polymictic conglomerates and intermediate to felsic intrusive rocks, which is analogous to major fault systems of the Timmins-Porcupine area and associated syn-orogenic Timiskaming conglomerates. The focus of this study is to examine the relationships between gold mineralization and deformation in the Detour Lake region and in Quebec and compare these with those of the southern Abitibi.
