Abstract

The carbonate strata of the Mackenzie Mountains of Northwestern Canada are host to a large number of mineralized base-metal occurrences, including the Neoproterozoic-hosted Gayna River deposit. Here, we present S and Pb isotopic data on sulphides and sulphates from Gayna River and 7 other smaller showings hosted by Lower Cambrian and Silurian-Ordovican units. The S isotope data suggest that the source of S in all the deposits is variable and may be derived locally. The Pb isotope data have consistent values for most of the showings suggesting a single Pb source for the mineralization. These data allow a model of a regional hydrothermal fluid flow event(s) in the Mackenzie Mountains in the Devonian-Carboniferous that deposited base metals in units of varying ages.
