(<b>d</b>) Close-up of a single layer of the kink band. The green and blue regions represent regions of opening and compression/compaction along the kink planes. The red circles mark the transition from compaction to opening. The black arrows along the bedding planes indicate bedding-parallel slip, which is activated during the kink band development due to the rotation of the lithons.
