Magnetic Polarity of Pillow Basalts from Reykjanes Ridge

A first attempt to measure directly the magnetic polarity of submarine basalts dredged from the Reykjanes Ridge indicates that the first two magnetic anomalies over the ridge resulted from a reversal of the earth's magnetic field. Volcanic criteria were used to determine the orientation the samples had before they were dredged from the sea floor.
