Capsule Geology

The Ram South showing is located 2 kilometres east of Inverted Peak.

The region is dominantly underlain by black shale of the Jurassic Fernie Group which unconformably overlies the Triassic Spray River Group comprised of indurated shale, mudstone and siltstone. The base of the Fernie Group is marked by a persistent pelletal phosphorite horizon that is 1 to 2 metres in thickness. These rock formations are regionally underlain by Pennsylvanian-Permian Rocky Mountain Group consisting mainly of dolomitic carbonate rock units. These units are exposed along the northeast limb of a broad syncline. Bedding along this limb averages a strike of 121 degrees with 18-degree dips southwest.

At the Ram South showing, phosphate nodules occur in a 5-metre-thick section of fine sandstone and siltstone of the Permian Johnson Canyon Formation (Ishbel Group). Nodules are up to 20 per cent by volume. Phosphate values range from 0.3 to 1.8 per cent P2O5 across a thickness of 1 to 1.5 metres (Section 41) (Open File 1987-16, page 66). This sequence overlies dolomite and silty dolomite of the Pennsylvanian Kananaskis Formation (Spray Lakes Group). The contact was not observed, nor was the contact with the overlying Triassic Sulphur Mountain Formation (Spray River Group).
