| Abstract | Comparison of magnetic properties of pillow basalts from the Rift Valley (FAMOUS area) and from the Crest Mountains (site 332 of DSDP Leg 37) of the Mid-Atlantic Ridge near 37°N shows that major differences in magnetic structure and properties of the oceanic crust occur between these two sites. Mean effective intensity of magnetization of the pillow basalt layer drops from 1.4 x 10 ² emu cm (4 A m ) at the axis to about 0.4 x 10 ² emu cm (4 A m at site 332). While the magnetic anomaly over the spreading center may be accounted for by a magnetized layer less than 500 m thick, deeper seated material contributes to the magnetic anomalies over the Crest Mountains.
