...MEHMET F. TANER Abstract “Les Mines Selbaie” is a large, generally low-grade, polymetallic (Zn, Cu, Ag, Au) “giant” volcanic-associated ore deposit in the Harricana-Turgeon belt, which is part of the northern Abitibi Subprovince of Quebec. Economically recoverable mineralization occurred in three...

...John E. Larson; Richard W. Hutchinson Abstract The Selbaie deposits of western Quebec are hosted in calc-alkalic pyroclastic rocks of the Abitibi subprovince. Rocks range upward from subaqueous debris flows through pumiceous tuff to densely welded ignimbrite; they form an intracaldera sequence over...

... N /Yb N = 1-4: Noranda camp (excluding the Horne deposit) and Val d'Or camp). Group III is host to only one known deposit, the Selbaie mine, which is unusual in that much of its mineralization cuts stratigraphy. The Selbaie mine sequence contains calc-alkalic andesite-rhyolite with relatively low...

...C. Tucker Barrie; T. E. Krogh Abstract The Selbaie mine is a large tonnage, low-grade Cu-Zn-Ag-Au deposit with both stratiform and epithermal characteristics. Mineralization comprises lower grade, disseminated Zn-Ag ore and pyritic siliceous sinter of the A1 zone at the surface; and higher grade Cu...

... Lake, Mattabi, Lyon Lake, Kamiskotia, South Bay and Selbaie—all from the Superior province of Canada ( Fig. 1 ), and the younger deposits include felsic volcanic rocks from the Bathurst camp, Canada; San Nicolas, Mexico; and Kuroko, Japan. Felsic metavolcanic rocks (the so-called "sericite...

... belt. Although considered less prospective, some districts dominated by FII rhyolites, such as Val-d’Or and Selbaie, have collectively produced in excess of 100 million metric tons (Mt) of ore. Deposits in these districts mainly consist of sulfide veins and disseminated ore with low Cu and Zn grades...

... an older till and of three dates obtained from intertill (below the surficial till) nonglacial sediments in the Timmins and Matheson areas in Ontario and the Selbaie mine area in Quebec, the oldest west-southwest (230–270°) striae are tentatively associated with the west-southwest flow that deposited...

..., and Selbaie). Systematic compressional wave velocity and density measurements in deep boreholes have established that lithological contacts were the main impedance contrast imaged, although reflections from faults and deformation zones have also been observed. The strongest reflections are attributed to mafic...

...). The Selbaie mine (47.3 Mt) is a polymetallic deposit within a caldera environment that has been in production for 23 years. At the mine, mineralization occurs in veins that cut the local strata at a high angle ( Bouillon 1990 ). Two high-resolution MCS profiles (29-1, 29-2) were acquired by Lithoprobe at Les...

...) and modal abundances of common sulfide minerals using simple mixing relations. Most sulfides have significantly higher impedances than silicate rocks, implying that seismic reflection techniques can be used directly for base metals exploration, provided the deposits meet the geometric constraints required...

...T. R. Hart; H. L. Gibson; C. M. Lesher Abstract Volcanogenic massive Cu-Zn-(Pb) sulfide (VMS) deposits occur primarily in subaqueous rift-related environments (e.g., oceanic, fore-arc, arc, back-arc, continental margin, or continental), are hosted primarily by bimodal, mafic-felsic volcanic...

.... Seismic reflection methods have been applied within a variety of geological environments in various mining camps in Canada, e.g., low-grade greenstone belts of the Archean Abitibi subprovince (Selbaie area, Perron et al., 1997 ; Matagami area, Milkereit et al., 1992a ; Ansil mine, Perron and Calvert...

... this money is unclear, but it could have significantly subsidized Selco's exploration expenditures. Selco used INPUT for massive sulfide exploration work in Canada. The first discovery was the South Bay deposit in 1967 and the second was Selbaie in 1974. In the latter case, the deposit had been detected...
