“…The Archean Abitibi greenstone belt of Quebec and Ontario contains a VMS tonnage of over 800 Mt (Galley et al 2007;Goutier et al 2011;Mercier-Langevin et al 2011). We focus on two VMS areas from the southern Abitibi belt: Kidd Creek (a large isolated deposit) and the Noranda district.…”

Volcanogenic massive sulfide (VMS) deposits and seafloor massive sulfide (SMS) deposits have a spatial and genetic connection with contemporaneous volcanism. The control exerted by the volcanic succession (e.g., rock type, architecture and facies) on the nature and style of the ore and alteration (e.g., subsea-floor replacement vs. exhalative, or discordant vs. conformable) is significant, making it imperative to understand the local volcanology in developing better genetic and exploration models.

“…1a,b). The Abitibi Subprovince contains over 800 Mt of known VMS ore Mercier-Langevin et al 2011), numerous orogenic gold deposits (e.g., Percival., 2007), and several other types of ores. The Lemoine auriferous VMS deposit is located in the Chibougamau mining district, in the NE corner of the Abitibi Subprovince (Fig.…”

High-Resolution Physical Properties, Geochemistry, and Alteration Mineralogy for the Host Rocks of the Archean Lemoine Auriferous Volcanogenic Massive Sulfide Deposit, Canada

Multi-parameter data on drill cores has a range of useful applications for ore deposit modeling and mineral exploration. Density, magnetic susceptibility, eight major elements, seven trace elements (portable X-ray fluorescence, pXRF), five mineral groups (near-infrared spectrometry) and average visible light reflectance were determined on rock cores from several drill holes. These are located near the Archean Lemoine auriferous volcanogenic massive sulfide (VMS) deposit in the Chibougamau mining district, Abitibi Subprovince, Quebec, Canada. This case study focuses on one drill hole in particular which has been recently characterized in detail by conventional methods (laboratory geochemistry, petrography, stable isotopes); this provides validation for the multi-sensor dataset. The best variables and immobile element ratios to distinguish between different lithological units in the multi-parameter data are density, magnetic susceptibility, Ti/Zr, Al/Zr, and Zr/Y. Downhole profiles of these parameters allow the four different felsic units in LEM-37, many of which are visually similar, to be distinguished, and geological contacts to be positioned precisely. Such methods would be even more useful in environments where recognition of primary characteristics is strongly hampered by intense hydrothermal alteration and superimposed deformation or metamorphism. Volcanic and intrusive rocks can be placed on classic diagrams to assign them names and magmatic affinities based on the corrected pXRF data. Downhole profiles of major and trace elements, combined with infrared mineralogy, allow hydrothermal alteration to be characterized, yielding results comparable to those of conventional techniques for the same drill hole, but with a much tighter spacing and within potentially shorter timeframes.

“…In ancient, deformed and metamorphosed terranes and/or belts, it may be difficult to establish the absolute timing of the precious metal enrichment in a VMS deposit. For example, in the 1980s Au was first thought to be synvolcanic in the Au-rich VMS deposits of the Doyon-Bousquet-LaRonde mining camp, then in the 1990s a syntectonic overprint was proposed, and more recently the Au has been confirmed to be part of the VMS-forming systems (Dubé et al, 2007b(Dubé et al, , 2014Mercier-Langevin et al, 2007a, b, 2009, 2011bWright-Holfeld, 2011;Yergeau, 2015;Yergeau et al, 2013Yergeau et al, , 2015, and references therein).…”
