Examples of oceanic core complexes (OCC) on the flanks of the Mid-Atlantic Ridge (MAR). Perspective views of colour-shaded seafloor morphology show structural components of OCC: shallow, corrugated domal cores that vary in depth along strike; termination of exposed detachment fault; adjacent hanging wall blocks; interpreted breakaway zone. White lines indicate selected MCS profiles. Seafloor perspectives modified from Canales et al. (2004); models modified from Tucholke et al. (1998).
