Regional Study of the Slave Point Formation – Cranberry N Area, NW Alberta


The study area is located in north western Alberta from Townships 100 to 106 and between Ranges 22W5 and 12W6. It is north of the Peace River Arch and of the buildups at Cranberry, Chinchaga, Snowfall and Hamburg.

The study area lies inboard of the main Slave Point margin to the north and west, on a broad carbonate platform influenced by a broad interior basin to the south east (Cranberry – Hotchkiss Embayment). The Slave Point Formation gradationally overlies the Fort Vermilion Formation carbonate mudstones and evaporites, and is in turn sharply overlain by the basin shales of the Waterways Formation. Across much of the Western Canada Sedimentary Basin the Slave Point Formation is a cyclic shallow water carbonate. However in this portion of the carbonate platform complex cyclicity in the Slave Point is less well defined largely due to the absence of any tidal flat sedimentation. Topographically the Slave Point Formation is comprised of a series of undulating carbonate shoal complexes. This topography is infilled by the regional regressive Beaverhill Lake basin shales of the Waterways Formation.

At the time of the study 113 wells penetrated the Slave Point Formation within the study area. A total of 24 cored wells (totaling more than 800 metres) were described at the AEUB Core Research Centre for this study.



The study area covers more than 100 townships (9,800 square kilometres):

  • 5 regional stratigraphic cross sections (2 dip & 3 strike);
  • 5 maps (2 isopach & 3 structure) at 1:150,000 scale;
  • stratigraphic picks and isopach values from Top Muskwa Fm. to Top Fort Vermilion Fm., including Muskwa Fm., Beaverhill Lake Fm., Slave Point Fm., and the Fort Vermilion Fm.;
  • 113 well database available in digital and hardcopy formats;
  • 24 core descriptions with internally consistent correlations.
