This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Boundary volcanogenic massive sulfide (VMS) deposit (0.45 Mt @ 3.4% Cu, 4.0% Zn, 1.0 % Pb, 34 g/t Ag) is located in the Tally Pond group (~510 Ma), central Newfoundland, Canada. The deposit is hosted by rhyolitic rocks that are interpreted to have formed within a rifted continental arc on the leading edge of Ganderia. Mineralization consists of massive pyrite, chalcopyrite, and sphalerite lenses. The basal portion of these lenses contain lapilli tuff clasts indicative of replacement style mineralization. Three hydrothermal alteration assemblages are recognized at Boundary: quartz-sericite, chlorite-sericite, and intense chlorite. Lithogeochemical data are useful in identifying key element associations and alteration assemblages. Short-wave infrared (SWIR) spectroscopy data provide an effective vector for Zn mineralization and correlate with whole rock geochemistry. Lithogeochemical and SWIR data have been used to recreate a three-dimensional alteration model of the Boundary deposit that may be useful in further mineral exploration.

Book Synopsis Mineralogy, Mineral Chemistry, and Genesis of Precious Metal-bearing Volcanogenic Massive Sulfide Deposits in the Newfoundland Appalachians, Canada by : Stefanie Michaela Brueckner
Download or read book Mineralogy, Mineral Chemistry, and Genesis of Precious Metal-bearing Volcanogenic Massive Sulfide Deposits in the Newfoundland Appalachians, Canada written by Stefanie Michaela Brueckner and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ming deposit, Newfoundland Appalachians, is a metamorphosed (upper greenschist to lower amphibolite facies), Cambro-Ordovician, bimodalmafic volcanogenic massive sulfide (VMS) deposit that consists of several, spatially-associated, elongated orebodies composed of stratabound semimassive to massive sulfides and/or discordant sulfide stringers in a rhyodacitic footwall. Copper is the main commodity; however, the deposit contains precious metal-bearing zones with elevated Au grades. In this study, field observations, microscopy, and micro-analytical tools including electron microprobe, laser ablation inductively coupled plasma mass spectrometry, and secondary ion mass spectrometry were used to constrain the relative timing of precious metal emplacement, the physico-chemical conditions of hydrothermal fluid precipitation, and the sources of sulfur, precious metals, semi-metals and metals. The ore mineral assemblage is complex and indicates an intermediate sulfidation state. Pyrite and chalcopyrite are the dominant ore minerals with minor sphalerite and pyrrhotite, and trace galena, arsenopyrite and cubanite. Additional trace phases include tellurides, NiSb phases, sulfosalts, electrum, AgHg±Au alloys, and oxides. Silver phases and precious metals occur predominantly in semi-massive and massive sulfides as free grains, and as grains spatially associated with arsenopyrite and/or sulfosalts. Precious metal phases occurring between recrystallized pyrite and within cataclastic pyrite are rare. Hence, the complex ore assemblage and textures strongly suggest syngenetic precious metal emplacement, whereas metamorphism and deformation only internally and locally remobilized precious metal phases. The ore assemblage formed from reduced, acidic hydrothermal fluids over a range of temperatures (≈350 to below 260oC). The abundance of telluride and Ag-bearing tetrahedrite, however, varies strongly between the different orebodies indicating variable ƒTe2, ƒSe2, mBi, and mSb within the hydrothermal fluids. The variations in the concentrations of semi-metals and metals (As, Bi, Hg, Sb, Se, Te), as well as Au and Ag, were due to variations in temperature but also to a likely contribution of magmatic fluids into the VMS hydrothermal system from presumably different geothermal reservoirs. Sulfur isotope studies indicate at least two sulfur sources: sulfur from thermochemically-reduced seawater sulfate and igneous sulfur. The source of igneous sulfur is the igneous footwall, direct magmatic fluid/volatiles, or both. Upper greenschist to lower amphibolite metamorphic conditions and deformation had no significant effect on the sulfur isotope composition of the sulfides at the Ming deposit.
