Microwave paleointensity analysis of historic lavas from Paricutín volcano, Mexico [PDF]
We report a microwave paleointensity study of historic lavas from Paricutin volcano, erupted during the period between 1943 and 1948. Most samples are characterized by uni-vectorial orthogonal plots.

Paleointensity is the variations in magnitude of the geomagnetic field in the near and remote past. Similar to paleodirectional studies, paleointensity research depends on the ability of a rock to preserve for a geologically long time the information related to the ambient magnetic field existing at the time the rock was formed.Paleointensity ...

Bulk magnetic domain stability controls paleointensity fidelity [PDF]
Nonideal, nonsingle-domain magnetic grains are ubiquitous in rocks; however, they can have a detrimental impact on the fidelity of paleomagnetic records—in particular the determination of ancient magnetic field strength (paleointensity), a key means of ...

Paleointensities are key to understanding the formation and evolution of Earth and are determined from rocks which record magnetic fields upon cooling; however, experimental protocols for estimating paleointensities frequently fail. The primary reason is

Variations of paleointensity in the Paleogene
Behavior of the geomagnetic field intensity in the Paleogene from sedimentary rocks of the Russian Plate was investigated. It is revealed that in the beginning of the Paleogene alternating of paleointensity variations of little amplitude (about 0.5 Ho, where Ho is the value of modern geomagnetic field taken as 40 mkT) and bursts of large amplitude (up ...

Abstract Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interstellar galactic cosmic rays and energetic particles of heliospheric origin.
