Two major deformation phases involving low grade metamorphism affect the Ordovician turbidite sequence known as the Mallacoota Beds. First‐generation F1folds are the dominant structures, generally occurring as tight, upright, gentle SSW‐plunging folds. These folds have been followed by Do‐deformation movements that generated folds (F2), kink bands and localised zones of S2crenulation cleavage. F2folds are locally present as open and upright folds that fold the F1structures into major SSE‐plunging warps. The resulting refolded F1structures are recumbent or inclined and in places reclined. All F1folds are parasitic and lie on a steep western limb of a major anticlinal structure, in which the stratigraphic sequences young in a westward direction. F1folds are produced during a single phase of regional deformation involving layer shortening of a partly lithified sequence, whereas the Do‐deformation involved localised shearing of a consolidated sequence.
