Cross-Section Formation of Magnetic Anomalies with Geologic Timescale |
| This block diagram illustrates the formation of magnetic anomalies for the last four epochs in the earth's magnetic reversal history. The first block diagram shows how mantle upwelling in response to ocean floor spreading produces magmas that form the oceanic crust during the reversed Gilber ... |

Magnetic Reversal Data and Timescale |
| The figure represents magnetic data taken from multiple locations around the world. It shows whether or not the samples were formed during a time that had a normal or reversed magnetic field. Each dot represents a different rock sample, which were then used to determine when the magnetic fiel ... |

Magnetic Reversals Based on Dipole and Nondipole Field Strength |
| The figure shows data for the different strengths of both the dipole and non-dipole fields. Magnetic reversals occur when the field strength of the non-dipole field is large relative to the strength of the dipole field. The data shows two reversals occurring at the beginning and end of segment T. |
