Our initial results indicate that this is the case for pyrite from the Geco ore body in northwestern Ontario, Canada. The precise determination of the age of sulphide ore deposits Cited by: the deposit and is composed of pyrite, sphalerite, galena, and chalcopyrite accompanied by quartz, ankerite, calcite, and chlorite. Grades average 3 percent Zn, percent Cu, and percent Pb, but this ore type has not been exten-sively mined (Large and Walcher, ).File Size: KB.

Pyrite is also widespread in a variety of ore deposits, particularly in hydrothermal deposits such as volcanogenic-hosted massive sulfides (VHMS), orogenic gold deposits, and Cu-porphyries (Large et al., , Maslennikov et al., , Reich et al., , Revan et al., , Thomas et al., ).

The Dome mine in Timmins Ontario has been in operation since (Holmes, ), producing over 16 million ounces of gold to date ().Like most world-class orogenic systems, the over 75 million ounces of gold produced in the Timmins gold camp, is the result of multiple mineralization events over a span of 7–25 Ma years (Proudlove et al., , Hutchinson, , Bateman and Cited by: 2. The Iberian Pyrite Belt (IPB) is recognized as having one of the major concentrations of volcanogenic massive sulfide (VMS) deposits on Earth. Original resources of about Mt of massive sulfides have been reported in the province. Recent classifications have considered the IPB deposits as the bimodal siliciclastic subtype, although major differences can be Author: Gabriel R.

It also may be found in radiating disks, hair-like crystals, concretions and massive lumps in sulphide ore deposits. Pyrite sometimes also contains small amounts of cobalt, nickel, silver or gold. indicated, copyright is held by the Queen’s Printer for Ontario.

Map of the Vermilion Lake pyrite deposits in the vicinity of the Vermilion Pyrite Mine, District of Rainy River; Ontario Bureau of Mines, Annual Report Map 20C, scale Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron.
Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.

The mineral pyrite (/ˈpaɪraɪt/), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS 2 (iron(II) disulfide). Pyrite is considered the most common of the sulfide minerals. Pyrite's metallic luster and pale brass-yellow hue give it Category: Sulfide mineral.

The Red Lake gold range, in Ontario, is continued westward in Manitoba. Northwest of Lake Winnipeg, a gold range begins at Wekusko Lake, and continues westward to and into Saskatchewan.
The isometric (cubic) polymorph of orthorhombic marcasite. Pyrite is a very common mineral (also one of the most common natural sulfides, and the most common disulfide), found in a wide variety of geological formations from sedimentary deposits to hydrothermal veins and as a constituent of metamorphic rocks.

Deposits of copper -bearing pyrite are widely distributed and often of great size. They usually occur in or near the contact of eruptive rocks with schists or slates. Pyrite weathers rapidly to hydrated iron oxide, goethite, or limonite. The S isotope composition of the detrital pyrite is compatible with an origin of S as dissolved sulfate in an ocean under a low oxygen atmosphere.
The potential source of the Au-bearing detrital pyrite appears to have been an, as yet, undiscovered Archean deposit located within 1 to 8 km of the placer by:. It is possible that other ores, the green silicates, garnierite, genthite, etc., may be found in Ontario in serpentine or peridotite.—South of Lake Shebandowan (West of Lake Superior), important values in nickel are found in a deposit of pyrite, chalcopyrite, pyrrhotite, polydymite and magnetite, in a long mineralized zone of chlorite and.Pyrite deformation in stratiform lead-zinc deposits of the Canadian Cordillera Article (PDF Available) in Mineralium Deposita 27(3) June with .Ontario ⓘ Bancroft area Grice, Joel D.
