Fig. 5: Shear wave velocity structure beneath the Mid-Atlantic Ridge.
From: Recycled arc mantle recovered from the Mid-Atlantic Ridge
a, b Horizontal slices through SL2013sv shear velocity tomographic model where percentage anomaly (dVs) is with respect to AK135 model at 150 and 300 km, respectively53; thick/thin black lines are spreading segments/fracture zones, respectively69. Stars denote 16°N segment. c Vertical slice along MAR shown in a, b; gray bands are major fracture zones, star is 16°N segment. d Black/gray line is ridge depth smoothed with 2000 km Gaussian filter. e Ridge depth smoothed with a 280 km Gaussian filter, compared with Vs (gray dots) along the MAR between 50°S and 55°N; star is 16°N segment.
