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 …

After many years spent by paleomagnetists studying the directional behavior of the Earth's
magnetic field at all possible timescales, detailed measurements of field intensity are now …

The time scale for marine magnetic anomalies for the Late Cretaceous through Neogene (C-
sequence) and Middle Jurassic through Early Cretaceous (M-sequence with deep-tow …

Recent advances in palaeomagnetic and dating techniques have led to increasingly precise
records of the relative intensity of the Earth's past magnetic field at numerous field sites. The …

Abstract Numerous 40Ar/39Ar experiments on sanidine and biotite from 22 ash beds and 3
volcaniclastic sand beds from the Greater Green River, Piceance Creek, and Uinta Basins of …

Midlatitude Asia (MLA), strongly influenced by westerlies-controlled climate, is a key source
of global atmospheric dust, and plays a significant role in Earth's climate system. However, it …

Speculation about its possible super-rotation has drawn the attention of many geophysical
researchers to the Earth's inner core. An issue of special interest for geodynamo modelling …

Sequential variations in manganese (Mn) content and color of deep-sea sediments retrieved
from the Lomonosov Ridge (87° N) in the central Arctic Ocean apparently mimic low-latitude …

Many geomagnetic excursions have been documented during the Brunhes Chron. However,
high-resolution paleomagnetic studies of sediments often provide evidence of few (if any) …

Earth's magnetic field is generated by fluid motion in the liquid iron core. Details of how this
occurs are now emerging from numerical simulations that achieve a self-sustaining …
