Post-[F.sub.2] structures include a sparsely developed set of chevron folds with horizontal axial planes ([F.sub.3]) and a poorly developed axial planar slaty cleavage ([S.sub.3]).
The earliest structural element developed in the Burtts Corner beds in this transect is a ubiquitous slaty cleavage ([S.sub.1]) in the more argillaceous lithologies.
An axial planar cleavage ([S.sub.2]) is penetrative in argillaceous units, where it is a slaty cleavage (lithons < 1 mm wide, Fig.
