Volcanogenic 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 کاملWhat processes at mid-ocean ridges tell us about volcanogenic massive sulfide deposits
Episodic seafloor spreading, ridge topography, and fault movement at ridges find (more extreme) analogs in the arc and back-arc setting where the volcanogenic massive sulfide (VMS) deposits that we mine today were formed. The factors affecting sulfide accumulation efficiency and the extent to which sulfides are concentrated spatially are the same in both settings, however. The processes occurri...
متن کاملDevono-Mississippian Felsic Volcanism Along the Western Edge of the Cassiar Terrane, North-Central British Columbia
The Late Devonian to Early Mississippian is an important metallogenic epoch within the Canadian cordillera resulting in the production of significant sediment exhalative massive sulphide (SEDEX) and volcanogenic massive sulphide (VMS) mineral occurrences within rocks of cratonic or pericratonic affinity. Major belts include the Late Devonian Earn-hosted SEDEX deposits of the Selwyn and Gataga d...
متن کاملGeology and Mineral Occurrences of the Upper Iskut River Area: Tracking the Eskay Rift through Northern British Columbia
The Eskay Creek gold-silver mine, located in northwest British Columbia, is the highest-grade precious-metal volcanogenic massive sulphide deposit in the world. The mining industry continues to spend more than $2 million each year on exploration for similar deposits in the area. The geologic setting at the minesite is well studied, but large tracts in north-central British Columbia require more...
متن کاملInvestigation of blind massive sulphide deposit signatures in the calcrete layers as a geochemical barrier: A case study of Areachap, Kantienpan and Copperton deposits
The trace element contents on the surface originated from mineralization would depend to the thickness of the calcrete layer above the ore deposit on the surface. A very thick layer of calcrete may not allow for much dispersion of the elements of interest in the surface. These elements may be concentrated in non-magnetic and magnetic part of calcrete. Based on the current research, mineralogica...
