cleavage banding

A compositional banding that is parallel to the cleavage rather than to the bedding. It results from the mechanical movement of incompetent material, such as argillaceous rocks, into the cleavage planes in a more competent rock, such as sandstone. Ordinarily, the argillaceous bands are only a few millimeters thick.
