This paper surveys 40 years of research on the processes by which a sediment acquires a
detrital remanent magnetization (DRM). These processes can be divided into two types …

The average frequency of geomagnetic reversals seen through a sliding window 10 my long
typically remains constant or nearly so for intervals of the order of 5× 107 years and then …

Topics involved in studies of the Earth's magnetic field and its secular variation range from
the intricate observations of geomagnetism, to worldwide studies of archeomagnetism and …

A new statistical model is proposed for the geomagnetic secular variation over the past 5 my
Unlike previous models, which have concentrated upon particular kinds of paleomagnetic …

William Gilbert first articulated what has come to be known as the geocentric axial dipole
hypothesis. The GAD hypothesis is the principle on which paleogeographic reconstructions …

Paleomagnetic pole positions have long been calculated with the assumption that the
ancient geomagnetic field was purely that of a geocentric dipole, but in recent years it has …

Persistent departures from the geocentric axial dipole field model of the time‐averaged
paleomagnetic field over the past 5 Myr have been analyzed using oceanic data from deep …

The proposal that the time‐averaged paleomagnetic field is not strictly that of a geocentric
axial dipole but that of an axial dipole displaced slightly northward from the geocenter is …

The available original archaeomagnetic world data on intensity and direction have been
compiled and sorted according to geographical region. Then, after correcting them to …

We review indications of persistent deviations from the geocentric axial dipole model of the
time‐averaged geomagnetic field and present a zonal harmonic model derived from 185 …
