Abstract
Gravity data from the Mid-Atlantic Ridge between latitudes 27°50′N and 30°40′N show that the accretion of magma at the ridge is focused at discrete centres along the spreading axis. Large positive gravity anomalies equivalent to reductions of almost 50% in crustal thickness are observed over non-transform discontinuities bounding spreading segments.
