AbstractThe 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.
Summary(Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI) is directed towards providing next generation knowledge and methods to facilitate more effective targeting of buried mineral deposits. The program aims to enhance the effectiveness of exploration for Canada¿s major mineral systems by resolving foundational geoscience problems that constrain the geological processes responsible for the liberation metals from their source region, transportation of these ore metals and control their eventual deposition. TGI supports projects on gold, Ni-Cr-PGE, porphyry-style mineralization, uranium and volcanic- and sedimentary-hosted base metal mineralization ore systems, with each project divided into subprojects focused on resolving specific knowledge gaps by integrating data and studies from multiple sites across Canada. Herein, we present interim results and interpretations from a selection of the research activities currently being conducted under the auspices of TGI.
