The effects of multiple deformation on a series of banded metasedimentary rocks is described. Disharmonic folding has occurred and a slide formed during the first phase of movement separates highly folded rocks from those above which are less deformed. The isoclinal recumbent folds of the first phase have been re-folded across steeply dipping axial planes to give a characteristic pattern of acurate outcrops. ater movements have produced open folds and rejuvenation of the slide. The development of faults and a fracture system is the final phase of deformation.
