The Ablation Point Formation at Belemnite Point consists predominantly of slump-folded and rafted blocks of turbidite sandstone interbedded with chaotic, mudstone-rich matrix. Deformation within the Ablation Point Formation varies from well-mixed sediment to coherently offset and imbricated slide sheets often bounded by well-defined low-angle faultsMacdonald, D.I., Moncrieff, A.C. and Butterworth, P.J., 1993.
