Three-dimensional magnetic stripes require slow cooling in fast-spread lower ocean crust

Earth’s magnetic field is recorded as oceanic crust cools, generating lineated magnetic anomalies that provide the pattern of polarity reversals for the past 160 million years 1 . In the lower (gabbroic) crust, polarity interval boundaries are proxies for isotherms that constrain cooling and hence c...
