Abstract

This study examines the geology, structure, hydrothermal alteration and mineralization from the Mazenod Lake volcanic complex in the Great Bear Magmatic Zone (GBMZ), Northwest Territories, Canada. Field work and geochemical data indicate that the Faber Group volcanic lithology is comprised of pervasively metasomatized, calc-alkaline, intermediate to felsic ignimbrite flows. Analysis of lineaments derived from a high-resolution satellite image and measured vertical gradient (MVG) aeromagnetic data delineate tectonic blocks defined by strike-slip faults, including two sets of NE-trending right-lateral faults (~N50°E and ~N20E°) and one set of left-lateral NW-oriented (~N30°W) faults. Mass balance and several diagnostic residual alteration indices (RAIs) characterize the nature, intensity and distribution of hydrothermal alteration. Spatial analysis of the RAIs reveals a direct correlation between locally significant structures and centers of intense alteration at Dan Island, Nod Hill and the central Bea area. The geology, structure and pervasive alteration are characteristic of a magmatic-hydrothermal iron oxide copper-gold (MH-IOCG) system.
