Plate divergence along mid-oceans ridges is accommodated through faulting and magmatic accretion (e.g., Bohnenstiehl & Carbotte, 2001; Cowie et al., 1993; Escartín et al., 2007) . Studies have shown that the long-term proportion of tectonic versus magmatic extension is highly variable and sensitive to spreading rate (Buck et al., 1998) , with the ratio of magmatic accretion over faulting higher along fast-spreading ridges (
