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 …

Crustal deformation patterns are affected by multiscale granulation and healing processes
associated with phase transitions between continuum and discrete states of rocks. The …

A series of computer simulations of the Earth's dynamo illustrates how the thermal structure
of the lowermost mantle might affect convection and magnetic-field generation in the fluid …

Abstract 80 years ago, Joseph Larmor planted the seed that grew into today's imposing body
of knowledge about how the Earth's magnetic field is created. His simple idea, that the …

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 …

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

Two recent studies of the geomagnetic field in the last 1Myr have found 14 excursions, large
changes in direction lasting 5–10kyr each, six of which are established as global …

The K‐Ar based geomagnetic polarity timescale was constructed using data from lavas and
tuffs that bracketed, but rarely dated, the transitions between polarity intervals. Subsequent …

The Ocean Drilling Program (ODP) has recovered many long sediment sequences from
around the World that contain medium to high-resolution paleomagnetic records of Brunhes …

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 …
