| Abstract | The Nanisivik Mississippi Valley-type Zn-Pb-Ag deposit is located on northern Baffin Island, Nunavut. Mesoproterozoic strata in the Nanisivik area consist of a basal siliciclastic succession (Adams
Sound and Arctic Bay formations), platformal carbonate deposits (Society Cliffs and Victor Bay formations),and a molasse deposit (Strathcona Sound Formation). These strata are cut by east-trending normal faults interpreted as the conduits for
mineralizing fluids that formed the Nanisivik massive sulphide deposits.Mineralization is localized within broad anticlines, proximal to normal faults, and is hosted by rocks of the upper and uppermost middle Society Cliffs Formation. Sulphide
precipitation is interpreted to be primarily the result of reduction of ascending metalliferous fluids by previously trapped hydrocarbons. Exploration criteria for the selection of areas prospective for additional Nanisivik-style mineralization
include stratigraphic, structural, and fluid-flow considerations. |
