Abstract

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.

摘要

首次尝试直接测量从雷克雅内斯海脊（Reykjanes Ridge）采集的海底玄武岩的磁极，结果表明，海脊上方的前两个磁异常是由地球磁场反转引起的。火山学标准被用来确定这些样本在从海底采集之前的方向。
