ROBEX Ba-Zn-Cu-Pb Deposit

Discovery Year: 1963
Location reference: Deposit located in a series of surveys. The drill cores of these surveys are situated at the junction of rank 20 and 21 and lots 51 and 52, in the Township of Upton (MB 86-46). The mineralized intersections are located approximately 10 m deep.
Comment - morphology: The mineralization of the Upton deposit is cluster-type quasi-layered. Host lithologies are oriented N070 ° general. The dip is 25 ° (GM 39067). The dimensions of the orebody are 350 m long x 300 m wide x 2 5m (MB 86-46).
Comment - lithology: The cluster lead-copper-zinc barite in Upton is confined to grainstones and packstones, crinoidal originally built from the limestone erosion (reef complex?). We observe in these rocks of order that centimetri laminations. Terrigenous sediments (black shales, siltstones) are interbedded it. All these lithologies are silicified. The mineral constituents mineralization are also carbonates, barite, sphalerite, pyrite, galena, chalcopyrite, and fluorite. These minerals occupy interstitial pore grainstones and packstones (MB 89-20). The mineralization of the lodging Upton is cluster-type quasi-layered, locally brecciated with barite, sphalerite, galena and chalcopyrit e. It also includes intersecting chalcopyrite and bornite veins. These veins zoned Zn-Pb-Cu appear later as described in Kumarapeli (1985). The limestone and mineralization as well as interbedded volcanics were taken by Appalachian outer laps so that you do not know if it is windows or mégablocs. Anyway, this tangential tectonic truncated flake clusters sulfur and sulfate (MB 89-20). Province: Appalachians.
Comment - Mineralization: The mineralization mineral constituents are also carbonates, barite, sphalerite, galena, chalcopyrite, pyrite and fluorite. These minerals occupy interstitial pore grainstones and packstones. Thus baryte sulfides and not fill the voids of the rock fragments replacing echinoderms and infiltrating stringer in clay interbedded. Sphalerite, honey yellow, occurs in zoned crystals in isolated aggregates and shows also of colloform textures. In many places, it surrounds echinoderm fragments. Galena is found in veinlets barite and calcite. It replaces locally sphalerite. Chalcopyrite is contemporary galena. Barite is black and is in rosettes (89-20 MB). This lead-copper-zinc and barium mineralization is complex. At Upton, there seems to be a shift from a dominant copper mineralization to another to lead zinc-barium. In detail, the paragenesis is no less complex. Sulfides are after the carbonates which is itself contemporary chalcopyrite. These two minerals can be included in pyrite (89-20 MB). Part of the min generalization consists of a calcite stringers network (5 mm to 10 cm) with chalcopyrite, bornite (up to 20% of the veins) and quartz. The veins are more or less parallel and show a zonation of the edge towards the center (calcite sulphide siliceous zone). Barite mineralization is treated as part of indultriels minerals.
Comment - substance: Levels: 2.98% Zn, 0.59% Pb, 0.11% Cd, 15.4 g / t Ag, 53.1% BaSO4 and 0.15% Cu over 11 m (survey no. 34, GM 17540, reported in GM 39067); 2.51% Zn, 0.49% Pb, 0.09% Cd, 7.2 g / t Ag and 61.9% BaSO4 13.6 m (survey no. 49, reported in 9067 GM 3).
Comment - structural control: Mineralization, which seems exhalative and contemporary to the deposition of sediment, would be controlled by the presence of syn-sedimentary faults that would channel hydrothermal solutions.
Comment - alteration: All lithologies located in the area are silicified mineralization (MB 89-20).
Type: Sulph. Exhalative in sediment rocks. (Sedex)
Comment - typology: Genesis: epigenetic and syngenetic area of a sedimentary exhalative deposit in carbonates. Rolled ore occurs in the interstices of the sediments or replace the fragments of echinoderms or is in veinlets within interbedded sandstone. The stratiform nature of the mineralization and the presence of fine and black barite suggests an underwater exhalative origin, pénécontempraine sedimentation (MB 89-20). Type: Sulphides Exhalative in sedimentary rocks (Sedex). Other: Three mine shaft of 7.6 to 18.3 m deep were dug near the western boundary of Lot 51 in line XXI. However, it does not appear to have been shipping ore from these pits, formerly known under the name Upton mine. This site is now one of the Upton Quarry, exloited for limestone.
