AbstractMetamorphosed volcanogenic massive sulphide deposits contain indicator minerals; however, little research has been carried out to determine which of these minerals may be useful for exploration in glaciated terrain. Few case studies have been published that document indicator minerals signatures in till around VMS deposits. To address this need, the indicator minerals that characterize the Izok Lake Zn-Cu-Pb-Ag VMS deposit, Nunavut, have been documented in bedrock and till down-ice. This report describes results for bedrock samples.
A suite of bedrock samples from mineralization and host rocks around the deposit were prepared and examined as polished thin sections and <2.0 mm heavy mineral concentrates. Selected indicator mineral compositions were examined using electron microprobe analysis. Indicator minerals that characterize the Izok Lake deposit, and will be useful for till surveys, include the ore minerals chalcopyrite, sphalerite, galena and pyrrhotite, as well as Zn-spinel gahnite, and the hydrothermal alteration mineral axinite.
