A 4 metre thick phosphatic interval occurs near the top of the Permian Ranger Canyon Formation (Ishbel Group) on Fairy Creek. The uppermost 2 metres average 1.35 per cent P2O5; the lower 2 metres average 0.32 per cent P2O5 (Open File 1987-16). Phosphate is in the form of ovoid nodules and very thin partings of massive phosphate along bedding planes.
