  2. Volcanogenic massive sulfide ore deposit - Wikipedia

    en.wikipedia.org/wiki/Volcanogenic_massive...

    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 produced by volcanic-associated hydrothermal events in submarine environments. [2] [3] [4] These deposits are also sometimes called volcanic-hosted massive sulfide (VHMS) deposits

  3. Massive sulfide deposits - Wikipedia

    en.wikipedia.org/wiki/Massive_sulfide_deposits

    Massive sulfide deposits are ore deposits that have significant stratiform ore bodies consisting mainly of sulfide minerals.Most massive sulfide ore deposits have other portions that are not massive, including stringer or feeder zones beneath the massive parts that mostly consist of crosscutting veins and veinlets of sulfides in a matrix of pervasively altered host rock and gangue.

  4. Seafloor massive sulfide deposits - Wikipedia

    en.wikipedia.org/wiki/Seafloor_massive_sulfide...

    Mineral associations may vary (1) in different mineralized structures, either syngenetic (namely, passive precipitation in chimneys, mounds and stratiform deposits) or epigenetic (structures that correspond to feeder channels, and replacements of host rocks or pre-existing massive sulfide bodies), or structural zonation, (2) from proximal to ...

  5. Hypogene - Wikipedia

    en.wikipedia.org/wiki/Hypogene

    Sulfur is a common component of the fluids, and most of the common ore metals, lead, zinc, copper, silver, molybdenum and mercury, occur chiefly as sulfide and sulfosalt minerals. [3] Examples of primary minerals formed in this way include the sulfide minerals pyrite (FeS 2), galena (PbS), sphalerite (ZnS), and chalcopyrite (CuFeS 2).

  6. Hydrothermal vent - Wikipedia

    en.wikipedia.org/wiki/Hydrothermal_vent

    The deposited metal sulfides can become massive sulfide ore deposits in time. Some black smokers on the Azores portion of the Mid-Atlantic Ridge are extremely rich in metal content, such as Rainbow with 24,000 μM concentrations of iron .

  7. Sedimentary exhalative deposits - Wikipedia

    en.wikipedia.org/.../Sedimentary_exhalative_deposits

    Sedimentary exhalative deposits (SEDEX or SedEx deposits) are zinc-lead deposits originally interpreted to have been formed by discharge of metal-bearing basinal fluids onto the seafloor resulting in the precipitation of mainly stratiform ore, often with thin laminations of sulfide minerals.

  8. Carbonate-hosted lead-zinc ore deposits - Wikipedia

    en.wikipedia.org/wiki/Carbonate-hosted_lead-zinc...

    World-wide distribution of MVT deposits (red), clastic sediment-hosted (green), and unclassified (blue) lead-zinc deposits. Source: USGS. Carbonate-hosted lead-zinc ore deposits are important and highly valuable concentrations of lead and zinc sulfide ores hosted within carbonate (limestone, marl, dolomite) formations and which share a common genetic origin.

  9. Kambalda type komatiitic nickel ore deposits - Wikipedia

    en.wikipedia.org/wiki/Kambalda_type_komatiitic...

    Kambalda-type ore deposits are distinctive in that the deposition of an immiscible Fe-Ni-Cu sulfide melt occurs within a lava flow channel upon the palaeosurface. This is distinct from other magmatic Ni-Cu-PGE deposits, where Fe-Ni-Cu sulfide melt accumulates within a subvolcanic feeder dike, sill, or magma chamber.
