Trace Element Geochemistry of Volcanogenic Massive Sulfide Deposits in Archean Greenstone Belts: Implications for Metal Endowment and Geodynamic Settings
… host world-class Au and base metal (Cu-Zn-Pb) massive sulfide deposits with distinct geological features, including a wide range of different host rocks and crustal settings. The range of settings is reflected in the trace metal signatures of their ores. This study examines the trace element …

Volcanic reconstruction of the paleoproterozoic powderhouse formation, Snow Lake, Manitoba, Canada: implications for controls on volcanogenic massive sulfide formation
… comprises the stratigraphic footwall to six volcanogenic massive sulfide deposits (VMS) at Snow Lake, Manitoba, Canada. It is interpreted to be a product of voluminous pyroclastic eruptions and concomitant subsidence followed by a period of relative volcanic quiescence that was dominated by …

Volcanic, structural, and hydrothermal controls on coincident Archean Low and High Sulfidation VMS Systems within the Onaman Assemblage, Onaman-Tashota Greenstone Belt, Northern Ontario, Canada
High sulfidation volcanogenic massive sulfide (VMS) deposits show characteristics of VMS and high sulfidation epithermal deposits and are suggested to have formed through magmatic fluid contribution to an evolved seawater hydrothermal system. Two superimposed systems within the Neoarchean Onaman …
