Abstract | In Vernon map area (82L) at least two stratigraphic assemblages link Quesnel terrane, Kootenay terrane and undivided metamorphic assemblages: 1) a Windermere-like biotite/hornblende- feldspar-quartz
assemblage; and 2) a carbonaceous schist, phyllite, argillite assemblage. Volcanic rocks, east of Vernon, thought to be Triassic and unconformable on older strata are likely part of an Eocene succession emplaced during crustal extension. Eocene
crustal extension was distributed across a broad area along steeply dipping faults; the horizontal component across north Okanagan Valley amounts to a few kilometres. Metallic mineral deposit types include porphyry copper and molybdenum, Kuroko-type
volcanogenic massive sulphide, skarn copper and gold, mesothermal gold, silver, and base metal veins, epithermal gold and silver veins and breccias, placer gold, and podiform chromite. Nonmetallic mineral occurrences include granite, sand and gravel,
limestone, marble, gypsum, clay, asbestos, soapstone, coal, agate, opal, jasper, wollastonite, fluorite, palagonite, silica, and kyanite. |
