VMS Deposits and their Associated Gold and Silver

  • GOLD IN VOLCANOGENIC MASSIVE SULFIDE DEPOSITS
    An overview of the variations of gold in massive sulfide ores from different deposits as well as variations within a single deposit. An understanding of the typical patterns will be helpful to the exploration for and the recovery of VMS deposits.

    Richard Walker of Westmin Resources Ltd.

  • THE GEOCHEMISTRY OF GOLD IN MODERN SEAFLOOR HYDROTHERMAL SYSTEMS
    A study of the geochemistry of gold in polymetallic massive sulfides, metalliferous sediments, sub-seafloor stock works and hydrothermal plumes in modern seafloor systems.

    M.D. Hannington is with the Geological Survey of Canada, Ottawa.

  • SUB-SEAFLOOR DEPOSITION OF SULFIDE AT THE TURNER-ALBRIGHT OPHIOLITE-HOSTED SULFIDE DEPOSIT, SOUTHWESTERN OREGON
    The Turner-Albright massive sulfide deposit occurs at the base of the pillow lava sequence of the late Jurassic Josephine ophiolite in the Klamath Mountains of southwestern Oregon. The slide show illustrates the geology and origin of this deposit along with reserve volumes and grades.

    A. Zierenberg has worked on massive sulphide deposits in the Java de Fucca ridge with the U.S. Geological Survey.

  • GENESIS OF THE GREENS CREEK VMS DEPOSIT, SOUTHEAST ALASKA: A GEOCHEMICAL STUDY
    A study of the late Triassic Greens Creek Volcanogenic Massive Sulfide deposit in southeastern Alaska with reserves grades and onnages. Mineralogy and similarities to other VMS deposits.

    Rainer Newberry, U.S. Geological Survey and Department of Geology and Geophysics, University of Alaska.

  • IMPLICATIONS FOR ORE GENESIS OF THE BATTLE LAKE, VANCOUVER ISLAND, BRITISH COLUMBIA VOLCANOGENIC MINERALISATION FROM A SULPHUR AND LEAD ISOTOPIC STUDY
    Describes an on-going sulphur and lead isotope study of the major ore bodies of the Battle Lake camp, Central Vancouver Island, British Columbia, postulating that the deposit precipitated from hydrothermal fluids that plumed into oxygenated, open ocean water.

    Collin Godwin is with the Department of Geological Sciences, University of British Columbia, Vancouver, British Columbia.

  • GEOLOGY OF WINDY CRAGGY DEPOSIT, NORTHWESTERN BRITISH COLUMBIA
    Study of the copper-cobalt-gold VMS deposit 200 km. southwest of Whitehorse, Yukon. Geology of the deposit derived from testing since 1958.

    M.P. Webster, Geddes Resources Ltd.

  • THE GEOLOGY AND GEOCHEMISTRY OF THE BLUE MOON POLYMETALLIC SULFIDE DEPOSIT, MARIPOSA COUNTY, CALIFORNIA
    A Kuroko-type VMS deposit hosted in Jurassic metavolcanic rocks of the Foothill Copper-Zinc belt. The slide show illustrates local geology and ore reserves.

    Rodney Graham, Monarch Resources Ltd., Venezuela

  • GENETIC ASPECTS OF THE SILVER PEAK VOLCANOGENIC MASSIVE SULFIDE DEPOSIT (OREGON) AND SIMILAR KUROKO DEPOSITS IN JAPAN
    Development of models for formation of the bedded portion of massive sulfide in Kuroko-type deposits in the Silver Peak region in Oregon with similarities in deposits in Japan.

    Robert Derkey, Washington Division of Geological and Earth Resources, Olympia, Washington.

  • THE SELBAIE ZN-CU-AG DEPOSITS, NORTHWESTERN QUEBEC: EVIDENCE FOR METALLOGENIC EVOLUTION FROM PRIMITIVE MARINE SUBAQUEOUS TO MATURE CONTINENTAL SUBAERIAL ENVIRONMENTS
    The Selbaie deposits of Northwestern Quebec are hosted in pyroclastic rocks of the Abitibi greenstone belt, representing an Archean volcanogenic setting that may have been more widespread in Archean time than previously thought.
