Abstract

A seismic reflection profile across the fracture zones on the Mid-Atlantic Ridge between 43° N and 44° N shows that the thickness of sediment increases markedly south of the fracture zone at 43° 05′ N on the eastern flank of the ridge. The thickness there is in accord with observations made west of the ridge in the region of the survey at 45° N. This suggests that the effects of rates of sea-floor spreading and sedimentation have been similar on this eastern part of the ridge to those west of the ridge farther north.
