    Theart et al. () and Schade et al. () noted that the structural hanging wall of the Copperton massive sulphide ore body displays geochemical characteristics of chloritization, typically. Massive sulfide, saprolite, and mineralized rock collected from diamond drill core and rotasonic core were analyzed to characterize the geochemical signature of the Bend mineralization and bedrock in the area of rotasonic drilling. Geochemical analyses characterizing each lithology are given in Woodruff et al. ().

    In the s, a new concept of sulfide ore deposition related to volcanic activity — volcanogenic massive sulfide deposits — led to widespread exploration activity by numerous companies for this type of deposit in the Lake Superior region. Along with new concepts of ore deposition came new technology to aid in the search for mineral Size: 7MB. The Hellyer massive sulfide deposit, with 17 Mt at 13 percent Zn, percent Pb, percent Cu, g/t Ag, and g/t Au, occurs within the Que-Hellyer Volcanics, a local component of the Cambrian Mount Read Volcanics (a × km belt of felsic, intermediate, and minor mafic volcanic rocks) that host all the large volcanogenic deposits.

Massive ore in volcanogenic massive sulfide deposits consists of greater than 40 percent sulfides, usually pyrite, pyrrhotite, chalcopyrite, sphalerite, and galena; non-sulfide gangue typically consists of quartz, barite, anhydrite, iron oxides, chlorite, sericite, talc, and their metamorphosed equivalents.

The overall mineralized interval consists of volcanogenic massive sulphides cut by a few metric mafic dykes which may contain remobilized sulphides. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): volcanogenic massive sulphides, gold veins.

Cummings VOLCANOGENIC MASSIVE SULPHIDE DEPOSITS ALAN GALLEY, MARK HANNINGTON AND IAN JONASSON Geological Survey of Canada, Booth Street, Ottawa, ON, K1A OE8 E-mail: [email protected] Definition Volcanogenic massive sulphide (VMS) deposits are also known as volcanic-associated, volcanic-hosted, and vol-cano-sedimentary-hosted massive sulphide.

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.

Not surprisingly, the way the mineralization is being folded and it plunges to the south, where the stringer zone smeared out, parallel to the massive sulphides.

The massive sulphide material varies from 1- 70 meters thick, this is unusual as most VMS deposits are less than 20 meters in thickness. known volcanogenic massive sulphide (VMS) ore lenses. Three-component VSP data acquired in an open borehole adjacent to the main orebodies of the camp are analysed here for this purpose.

Ideally, VSP data would be acquired through the depth interval of an orebody, allowing certain identification of the seismic response from the mineralized zones. Purchase Treatise on Geochemistry - 2nd Edition. Print Book & E-Book.

The Restigouche volcanogenic massive sulfide (VMS) Zn-Pb-Cu deposit in north-central New Brunswick is m long, averages 90 m wide by 30 m thick, c.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.
