We review the ages of Quaternary magnetic polarity reversals and magnetic excursions.
Improvements in radioisotopic 40 Ar/39 Ar dating of reversals and excursions reflect the use …

Reversals and excursions of Earth's geomagnetic field create marker horizons that are
readily detected in sedimentary and volcanic rocks worldwide. An accurate and precise …

Coupled relative geomagnetic paleointensity (RPI) and oxygen isotope records are used to
construct RPI and oxygen isotope stacks for the last 1.5 Myr. The coupled correlations are …

Independent records of relative magnetic palaeointensity from sediment cores in different
areas of the world can be stacked together to extract the evolution of the geomagnetic dipole …

Paleomagnetic records from sediments, archeological artifacts, and lava flows provide the
foundation for studying geomagnetic field changes over 0–100 ka. Late Quaternary time …

The “hard” isothermal remanent magnetization (HIRM) and the S‐ratio are widely used in
environmental magnetism to quantify the absolute and relative concentrations, respectively …

We present a new time-varying model for palaeomagnetic axial dipole moment (PADM) for
the past 2 Myr and compare it with earlier virtual axial dipole moment (VADM) …

Geomagnetic excursions are short‐lived episodes when Earth's magnetic field deviates into
an intermediate polarity state. Understanding the origin, frequency, amplitude, duration, and …

Component natural remanent magnetizations derived from u-channel and 1-cm3 discrete
samples from ODP Site 919 (Irminger Basin) indicate the existence of four intervals of …

Reversal of Earth's magnetic field polarity every 105 to 106 years is among the most far-
reaching, yet enigmatic, geophysical phenomena. The short duration of reversals make …
