a) Bathymetry from the 13 N region of the Mid-Atlantic Ridge. Gray shading indicates two core complexes that have formed in the middle of a spreading segment. The box is the region interpreted in (b). Black lines: borders of the MAR ridge axis, the tops of rotated faults, and schematic striations on core complexes. B: basins that have formed during the outward rotation of the tops of the faults. b) Line drawing of the bathymetry in the box in (a) showing striated core complexes and the tops of rotated faults. B: basins as in (a). At the spreading axis, axial volcanic ridges are outlined in black. Red areas indicate that volcanism occurs along the axis. Blue line: location of the profile shown below. c) Schematic profile across the southern core complex similar to the profiles shown in Figure 1. Striations on the exposed footwall are labeled. LR: linear ridge created by the outward rotation of the top of a fault. Faulted sections of brown-shaded material on the top of the core complex surface are rafted blocks of the median valley floor.
