Multidisciplinary studies of the slow-spreading (<30 mm a-1) ridge axis in the MARK Area define a number of discrete spreading cells in each of which the style of seafloor spreading is distinctly different. In some cells, episodic magmatism and asymmetrical detachment faulting occur, whereas in others, a more continuous magma supply and symmetrical, steep, normal faulting dominate. Oblique-slip fault zones that link the cells are a kinematic requirement of such along-strike variations and are similar to the accommodation or transfer zones of continental rifts. -Authors
