AbstractMiddle and Upper Devonian carbonate deposits in northeastern Alberta were investigated in outcrop and core for their Mississippi Valley-type (MVT) lead and zinc potential. A detailed petrographic study indicates that many, but not all, of the diagenetic products associated with the Pine Point - Presqu'ile Barrier deposits were found. Isotopic analysis of the rocks suggests the diagenetic fluid(s) responsible for dolomitization in the area was modified Devonian seawater. Stable isotope data from the Mikkwa Formation at Harper Creek, and the Methy Formation at Whitemud Falls, fall within, or are marginal to similar studies on the Pine Point - Presqu'ile Barrier deposits. 87Sr/86Sr values from the Mikkwa Formation at Harper Creek and Vermilion Chutes show some similarities to Pine Point dolomite data. Overall, the integrated data do not rule out the possibility of MVT Pb-Zn deposits in northeastern Alberta, but do not support exploration at the sites examined.
