Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and created by volcanic-associated hydrothermal events in submarine environments.

These deposits are also sometimes called volcanic-hosted massive sulfide (VHMS) deposits. The density generally is kg/m 3. ISBN: OCLC Number: Description: v, pages: illustrations, maps ; 29 cm. Contents: The history of mining and metallurgy in Latin America, BC AD / Robert J. Cathro --Volcanogenic massive sulphide deposits of Latin America: an overview / Ross Sherlock and Michael Michaud --The Guerrero terrane of western Mexico: geology and massive sulphide.

The data was recently used for mineral-deposit density models (Mosier and others, ; Singer, ). In this paper, deposits were used to construct revised grade and tonnage models.

Our new models are based on a reclassification of deposits based on host lithologies: Felsic, Bimodal-Mafic, and Mafic volcanogenic massive sulfide deposits. If we start with VMS Volcanogenic Massive Sulphide Ore Deposits and their Mineralization we see from this image shows some of the sulphide chimneys associated with the model black smoker VMS deposit.

VMS will emit black plume of hot water venting from one of the chimneys. You’ll remember this cross section from reads on both porphyry deposits and epithermal, in the case of VMS deposit, we.

In book: VMS Deposits of Latin America, Publisher: Geological Association of Canada, Editors: Ross Sherlock, pp   Volcanogenic massive sulfide (VMS) deposits are mineral accumulations that form on or near the seafloor at sites of high-temperature hydrothermal vent fluid discharge.

The deposits are formed by the precipitation of dominantly sulfide minerals around hydrothermal vents (e.g., black and white smokers) where high-temperature, metal- and sulfur-rich fluids mix with cold seawater.

Volcanogenic massive sulphide (VMS) deposits are also known as volcanic-associated, volcanic-hosted, and vol-cano-sedimentary-hosted massive sulphide deposits. They typically occur as lenses of polymetallic massive sulphide that form at or near the seafloor in submarine volcanic envi-ronments.

They form from metal-enriched fluids associated. Volcanogenic massive sulfide deposits, also known as volcanic-hosted massive sulfide, volcanic-associated massive sulfide, or seafloor massive sulfide deposits, are important sources of copper, zinc, lead, gold, and silver (Cu, Zn, Pb, Au, and Ag).

These deposits form at or near the seafloor where circulating hydrothermal fluids driven by. Volcanogenic massive sulfide deposits (VMS) are grouped into five lithostratigraphic types, using sequence boundaries defined by major time-stratigraphic breaks, faults, or major (subvolcanic) intrusions: (1) bimodalmafic settings (e.g., Noranda, Urals) occur in incipient-rifted suprasubduction oceanic arcs, typified by flows and.

Other articles where Volcanogenic massive sulfide is discussed: mineral deposit: Volcanogenic massive sulfides: Wherever volcanism occurs beneath the sea, the potential exists for seawater to penetrate the volcanic rocks, become heated by a magma chamber, and react with the enclosing rocks—in the process concentrating geochemically scarce metals and so forming a hydrothermal.

The main objective of this paper is to identify the geochemical, hydrological, igneous and tectonic processes that led to the variations in the physical (size, geometry) and chemical (mineralogy, metal ratios and zoning) characteristics of volcanogenic massive sulfide deposits with respect to space (from a scale of mining district size area to a global scale) and time (from a.

Volcanic-associated massive sulfide deposits (VMS) are predominantly stratiform accumulations of sulfide minerals that precipitate from hydrothermal fluids at or below the seafloor, in a wide.

Before the late 's, the VMS class of deposits was unknown. Bateman () noted that the Flin Flon deposits formed "by hydrothermal replacement of a large shear zone by solutions that emanated from the granite magma reservoir". Lindgren () presciently related VMS deposits to "iron-magnesium, high-temperature metasomatism".VMS deposits Volcanogenic massive sulfide deposits: Information on VMS deposits from around the world with new grade and tonnage models for three subtypes of VMS deposits and data allowing locations of all deposits to be plotted using GIS.

Volcanogenic massive sulfide deposits contain variable amounts of gold, both in terms of average grade and total gold content, with some VMS deposits hosting world-class gold mines with more than t Au. Previous studies have identified gold-rich VMS as having an average gold grade, expressed in g/t, exceeding the total abundance of base metals, expressed in wt.%.
