Eos, Transactions American Geophysical Union, 1989 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 ...

Behavior of paleointensity during the Paleogene [PDF]
Physics of the Earth and Planetary Interiors, 2014 Abstract Behavior of the intensity of geomagnetic field in the Paleogene was studied by the analysis of the sedimentary rocks of the Russian Plate. It is revealed that in the beginning of the Paleogene the variations of little-amplitude paleointensity (about 0.5 H 0 , where H 0 is the value of modern geomagnetic field taken as 40 μT) were ...

Revisiting the Jurassic Geomagnetic Reversal recorded in the Lesotho Basalt (Southern Africa)
, 2003 We carried out a detailed and continuous paleomagnetic sampling of the reversed to normal geomagnetic transition recorded by some 60 consecutive flow units near the base of the Lesotho Basalt (183 1 Ma).

Near-seafloor magnetic mapping of off-axis lava flows near the Kairei and Yokoniwa hydrothermal vent fields in the Central Indian Ridge [PDF]
, 2018 The Kairei (KHF) and Yokoniwa hydrothermal fields (YHF) are hosted in mafic as well as ultramafic rocks distributed at an off-axis volcanic knoll of the Central Indian Ridge.

Resolving the Internal Magnetic Domain Structure of Cloudy Zone Tetrataenite
Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Recent advances in magnetic imaging can directly capture the internal magnetization of natural and synthetic materials at resolutions <10 nm. This capability opens new possibilities to determine the magnetic domain state of ferromagnetic minerals that are fundamental for recording and retaining paleomagnetic records.

Establishing a Lunar Origin for Paleomagnetic Records in Apollo Samples
Geophysical Research Letters, 2023 Numerous paleomagnetic studies attribute the magnetization preserved within Apollo samples to an ancient dynamo. However, other works propose that lunar rocks were instead magnetized by either transient impact‐related magnetic fields on the Moon or by ...

Cryptic Paleomagnetic Complexity in the Ediacaran Egersund Dikes
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract The Ediacaran Period (∼635–539 Ma) represents a critical interval in Earth's evolution, yet its paleomagnetic record remains complex and contentious. One of the few Ediacaran paleomagnetic results from Baltica considered robust is a pole from the ca.

An attempt to determine the microwave paleointensity on historic Paricutín volcano lava flows, Central Mexico [PDF]
Geofísica Internacional, 2003 We report a preliminary rock-magnetic and microwave paleointensity study of historic lava flows between 1943 and 1948 of Paricutín volcano. These lava flows show well-preserved, well-exposed, fresh and extensive outcrops.
