Magnetostratigraphy involves the study of changes in the Earth's magnetic field that are recorded in sediments and rocks. These include short‐term fluctuations (secular variation), polarity transitions and magnetic reversal sequences. All have important applications in the Earth sciences. They can be used to calculate the rates of sea‐floor spreading and sediment deposition rates, and for time‐correlation of rock sequences, especially when no other means are available.
