AbstractA regional study undertaken south and west of Great Slave Lake, Northwest Territories, focused on evaluating the fluids associated with lead-zinc mineralization in the Pine Point mining camp. Microthermometric studies identified two fluid types: Type 1 fluid was observed in sphalerite and dolomite, and is a moderately low-temperature (respective ave. 86 and 100°C), high-salinity calcic brine (ave. 25 to 27 wt. % CaCl2-NaCl), that was directly involved in the processes that deposited the metals; Type 2 fluid, observed in calcite and celestite, is slightly lower in temperature (~85°C), is less saline (ave. ~9 wt. % CaCl2-NaCl), and was not involved in metal deposition.
