Geology and Hydrothermal Alteration of the Mercur Gold Deposit, Utah
The term "Carlin-type" deposit has been applied to a number of low-grade, sedimentary rock-hosted gold deposits that have been discovered and brought into production in the western United States since the 1960s. Carlin-type deposits are characterized by replacement of carbonate and silty carbonate rocks by silica, pyrite, barite, various arsenic, mercury, antimony, and thallium minerals and by ...
متن کاملGeology and Alteration at the Mount Milligan Gold-copper Porphyry Deposit, Central British Columbia
The Mount Milligan deposit, centred at latitude SS”O8’ north and longitude 124”04’ west, is 100 kilometres westsouthwest of Mackenzie and 160 kilometres northwest of Prince George in central British Columbia. The deposit occurs in gently rolling topography (Plate 2-6-l) 5 kilometres due south of Mount Milligan. Access to the property is by a 93.kilometre logging road that connects with the Hart...
متن کاملGeochemical and mineralogical characteristic of the VHMS alteration pipe, major elements variations and peraluminous ratio, in high grade metamorphosed rocks
The massive sulphide deposit at Kantienpan Cu-Zn mine is hosted by volcano sedimentary succession known as the Areachap Group, in the eastern part of Namaqua Metamorphic Province, South Africa. The deposits were affected by a complex deformation and metamorphic history and represent examples of upper amphibolite to granulite grade metamorphosed volcanic-hosted m...
متن کاملHeavy Metal Contamination and Mobility at the Mine Area of Draa Lasfar (Morocco)
The present study represents a first insight into the Draa Lasfar mine (Marrakech) to assess the possible diffusion of heavy metals and to predict the risk of their mobility in the surroundings of the mine area. The edaphologic parameters pH, electrical conductivity (EC), loss on ignition (LOI) and CaCO3 were measured according to standard methods, whilst heavy metals concentration was determin...
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...
