AbstractCarbonate-hosted Zn-Pb deposits of the Kootenay Arc are hosted by deformed Lower Cambrian, platformal carbonate rocks of the Badshot Formation or its equivalent, the Reeves member of the Laib Formation. The deposits range in size from 6 to 10Mt and contain 3 to 4%Zn, 1 to 2%Pb, 0.4% Cd, and traces of Ag. They are essentially stratabound and stratiform lenticular concentrations of sulphide minerals
(sphalerite, galena, pyrite, local pyrrhotite, and rare arsenopyrite) in isoclinally folded dolomitized or silicified carbonate rocks. The origin of these deposits is enigmatic. Some are analogous in their geological setting and features to the Irish-type carbonate-hosted Zn-Pb deposits.
