Steven E. Peter, AGAT Laboratories


The Crossfield Member of the Wabamun Group in the Lone Pine Creek area of southwestern Alberta consists of very finely to medium crystalline dolomites, deposited as a part of a north-south trending bank generally along the Fifth Meridian. The Crossfield Member represents the porous part of a shallowing upward carbonate cycle, which is capped by laminated and anhydritic dolomites. A shallower, algal facies dominates the reservoir at Lone Pine Creek, compared to Crossfield East where stromatoporoid dolorudstones prevail.
