Comments on the geologic information

  • Geologic Description = Native copper and malachite and azurite stains are present at two localities in basalt that is locally amygdalordal. Azurite and malachite is present in breccia zone in Devonian or older dolomite overlying the basalt.??These dolomites are likely part of the Katakturuk Dolomite which depositionally overlies the basalt in which the copper is present. The Katakturuk Dolomite is considered Proterozic in age and hence the basalt also likely is Proterozoic in age.
  • Age = Probably Proterozoic
