AbstractMineralized and non-mineralized coarse-crystalline dolomite (CCD) and saddle dolomite (SD) in Devonian carbonate rocks of the northern Rocky Mountains and the Western Canada Sedimentary Basin are compared in terms of fluid inclusion microthermometry and stable and radiogenic isotopic characterization. Samples from the Western Canada Sedimentary Basin are divided into four areas: eastern Presqu'ile barrier, western Presqu'ile barrier, McDonald-Hay River Fault system, and the Peace River Arch.
Isotopic trends point to easterly formation-fluid flow paths from the Rocky Mountains to the western continental platform, and a key role for the northeast-trending structures in the circulation and focusing of hydrothermal and mineralizing fluids.
Two distinct lead isotopic populations exist in sulphides from the carbonate-hosted Zn-Pb occurrences of the northern Canadian Rocky Mountains, Mackenzie Mountains, and Western Canada Sedimentary Basin, suggesting that two separate fluid sources/pathways existed in the Western Canada Sedimentary Basin.
