When was the mid-ocean ridge magnetic striping pattern discovered?
Earth scienceGeophysics
Quick Answer
In the early 1960s, especially after 1963, when scientists identified symmetrical magnetic anomalies on either side of ridges.
The Full Story
The striking magnetic stripes on the seafloor were recognized in the early 1960s as ocean surveys expanded. Researchers found alternating bands of normal and reversed magnetic polarity arranged symmetrically around mid-ocean ridges. In 1963, Vine and Matthews linked these stripes to seafloor spreading and geomagnetic reversals. That discovery provided powerful evidence that new crust forms at ridges and moves outward over time.
