F1 macroscopic folds in the Late Palaeozoic Coffs Harbour Beds in the SE portion of the New England Fold Belt are commonly transected by cleavage. These macroscopic folds are tight to isoclinal structures, with a consistent vergence to the NE. Axial surfaces are either steeply dipping to the SW or vertical, and are typically faulted. Anomalous bedding-cleavage relations occur where the steeply dipping cleavage intersects overturned limbs of F1 macroscopic and some F1 mesoscopic folds. Elsewhere F1 mesoscopic folds have a well developed, axial-surface cleavage and are rarely downward facing. Cleavage is commonly strike-divergent from axial surfaces of F1 macroscopic folds, except adjacent to the Demon Fault System, where they are parallel. These anomalous cleavage-folds relations possibly developed during the one deformation. D1 structures are refolded by kink-like folds that are steeply plunging. The structural style of the D1 deformation indicates that it possibly resulted from accretionary processes at a consuming plate margin. |
