Summary. The quality of marine magnetic anomaly sources is described with the power‐density representation of a stochastic model of random temporal and spatial emplacement of the marine magnetic anomaly source in the oceanic crust. Typical values of sea‐floor spreading and emplacement parameters define a high‐fidelity process of recording and sea‐surface detection of the palaeomagnetic field reversals for spreading rates over 20 mm yr ‐1 . An analogous stochastic model is developed for the formation of sea‐floor topography by normal faulting. It is shown that the random process of normal faulting observed in the inner walls of the FAMOUS rift valley can account for the quality of the adjacent West Rift Mountains topography.
