The 0.85–0.55 Ga Arabian-Nubian Shield of northeast Africa comprises an assemblage of volcanic arc and sub-arc strata that are fertile for volcanogenic massive sulphide (VMS) and overlying oxide gold deposits. At least fifty VMS deposits are known

Volcanogenic massive sulfide (VMS) districts are typically ~40 km in diameter and contain about a dozen regularly spaced Zn-Cu orebodies, one or two of which contain more than half of the district’s resources. We numerically investigate this deposi

The Neoproterozoic Bisha volcanic-associated massive sulfide deposit (VMS) is a large (>39 million metric tons (Mt)) relatively high grade Zn-Cu-Au-Ag deposit in a newly discovered VMS district in western Eritrea. The host stratigraphic section compr

The Paleoproterozoic Ruttan Cu–Zn volcanogenic massive-sulfide (VMS) deposit is a large, relatively low grade, bimodal-siliciclastic type deposit in the Rusty Lake volcanic belt of northern Manitoba. The deposit contained over 82.8 million tonnes o

Paleosea-floor, volcanic-associated massive sulfide mineralization has been discovered 50 to 150 m upsection from a Late Archean peridotitic komatiite flow, where the flow is thickest in a thermal erosion channel. The Terminus massive sulfide occurre

The Selbaie mine is a large tonnage, low-grade Cu-Zn-Ag-Au deposit with both stratiform and epithermal characteristics. Mineralization comprises lower grade, disseminated Zn-Ag ore and pyritic siliceous sinter of the A1 zone at the surface; and highe

Studies of plutonic rocks in Archean terranes such as the southern Abitibi subprovince have been an important component in the development of an accretionary tectonic model for the Superior province. In the southern Abitibi subprovince, pretectonic (
