Atmospheric sulfur in Archean komatiite-hosted nickel deposits.
Some of Earth's largest iron-nickel (Fe-Ni) sulfide ore deposits formed during the Archean and early Proterozoic. Establishing the origin of the metals and sulfur in these deposits is critical for understanding their genesis. Here, we present multiple sulfur isotope data implying that the sulfur in Archean komatiite-hosted Fe-Ni sulfide deposits was previously processed through the atmosphere a...
متن کاملThermal and Fluid Dynamics of Komatiitic Lavas Associated with Magmatic Fe- Ni-Cu-(PGE) Sulphide Deposits
The most important examples of magmatic ore deposits in volcanic rocks are Fe-Ni-Cu-(PGE) sulphides associated with Archean and Proterozoic komatiitic lava channels (Lesher, 1989). Komatiitehosted ores contain ~25% of the world’s nickel sulphide resource (≥ 0.8% Ni), including significant amounts of copper and platinum group elements (Ross and Travis, 1981). Field, experimental, and theoretical...
متن کاملKUSHK ZINC-LEAD DEPOSIT A TYPICAL BLACK-SHALE-HOSTED DEPOSIT IN YAZD STATE, IRAN
Kushk zinc- lead deposit is located about 167 km east of the city of Yazd, Iran. The geographical location of the mine is 31°, 40' N and 55", 40' E. Different rock types including volcanics and subvolcanics (rhyolites, rhyodacites, dacites, and rhyolitic tuffs) and sedimentary rocks (shale, limestones and dolomites) crop out in the area. Mineralization of the deposit occurs in black shale o...
متن کاملVolcanogenic Massive Sulphide Deposits
Volcanogenic massive sulphide (VMS) deposits are also known as volcanic-associated, volcanic-hosted, and volcano-sedimentary-hosted massive sulphide deposits. They typically occur as lenses of polymetallic massive sulphide that form at or near the seafloor in submarine volcanic environments. They form from metal-enriched fluids associated with seafloor hydrothermal convection. Their immediate h...
متن کاملPotential for New Nickel-Copper Sulfide Deposits in the Lake Superior Region
Scientists from the U.S. Geological Survey are evaluating the potential for undiscovered sulfide deposits containing varying amounts of nickel, copper, platinumgroup metals, and cobalt in the Lake Superior region as part of an ongoing effort to assess the mineral potential of the United States. Similarities between rocks of the Midcontinent rift and rocks that host the Voisey Bay nickel-copper-...
