Aqueous Geochemistry and Mineralogy of Tungsten with Emphasis on Mine Wastes

Autor: B. G. Kazamel, H. E. Jamieson, M. I. Leybourne, H. Falck, K. H. Johannesson

Publikováno v: Economic Geology. 118:659-674

Tungsten is a valuable industrial metal with limited effective substitutes for its many industrial uses. Tungsten is classified as a critical mineral by many countries, including Canada and the United States. As such, tungsten mining is expected to i

Thallium isotopes as indicators of ore mineralization at the Zn-rich sediment-hosted massive sulfide TL Deposit, British Columbia, Canada

Autor: Derek R. Knaack, K. V. Sullivan, M. I. Leybourne, C. E. Dunn, D. Layton-Matthews

Publikováno v: Geochemistry: Exploration, Environment, Analysis. 23

Few studies have focused on the application of the Tl isotopic system for geochemical exploration. We report ε 205 Tl values of rock samples from the TL Deposit, British Columbia, Canada – a sediment-hosted massive sulfide (SHMS) deposit with char

Indicator minerals in fine-fraction till heavy-mineral concentrates determined by automated mineral analysis: examples from two Canadian polymetallic base-metal deposits

Autor: H D Lougheed, M B McClenaghan, D Layton-Matthews, M I Leybourne

Exploration under glacial sediment cover is a necessary part of modern mineral exploration in Canada. Traditional indicator methods use visual examination to identify mineral grains in the 250 to 2000 µm fraction of till heavy-mineral concentrates (

Geochemical data for stream and groundwaters around the Casino Cu-Au-Mo porphyry deposit, Yukon (NTS 115 J/10 and 115 J/15)

Autor: J A Kidder, M B McClenaghan, M I Leybourne, M W McCurdy, P Pelchat, D Layton-Matthews, C E Beckett-Brown, A Voinot

This open file reports geochemical data for stream and groundwater samples collected around the Casino porphyry Cu-Au-Mo deposit, one of the largest and highest-grade deposits of its kind in Canada. The calc-alkaline porphyry is hosted in a Late Cret

Geochemical evidence for a magmatic contribution to the metal budget of the Windy Craggy Cu-Co(±Zn) volcanogenic massive-sulfide deposit, northwestern British Columbia

Autor: M I Leybourne, J M Peter, M A Schmidt, D Layton-Matthews, A Voinot, L Mathieu

Volcanogenic massive-sulfide (VMS) deposits may have had metal contributions from magmatic degassing and leaching of footwall rocks. The Windy Craggy Cu-Co-Zn VMS deposit in northwestern British Columbia may include magmatic contributions, based on l

Form and distribution of gold mobilized into surface waters and sediments from a gossan tailings pile, Murray Brook massive sulphide deposit, New Brunswick, Canada

Autor: D R Boyle, M I Leybourne, Wayne D. Goodfellow, Gwendy E.M. Hall

Publikováno v: Applied Geochemistry. 15:629-646

Stream waters and sediments draining a gossan tailings pile at the Murray Brook massive sulphide deposit were collected to investigate Au mobility. Weathering of the massive sulphides at Murray Brook during the Late Tertiary period resulted in the co
