Limitations in correlation of regional relative geomagnetic paleointensity [PDF]
Geochemistry, Geophysics, Geosystems, 2006 Time domain correlations of common features among relative paleointensity records from sedimentary cores are invaluable to paleomagnetism and paleoclimatology. Sediments with high accumulation rates might now provide millennial scale correlations of temporal variations in the geomagnetic dipole moment.

Geochemistry, Geophysics, GeosystemsAnisotropy of magnetic remanence (AMR) holds promise for quantifying relative paleointensity values from sedimentary rocks. A proof of concept was established for applied fields that exceeded the intensity of the geomagnetic field.

Geochemistry, Geophysics, GeosystemsMarine sediments contain magnetic mineral particles of detrital, biogenic and authigenic origin that record changes in the direction and intensity of the geomagnetic field over geological time.

The necessity of data availability in maintaining the value and longevity of paleointensity results
Frontiers in Earth Science, 2014 Asserting the reliability of paleointensity estimates, or comparing relative reliabilities between vastly or subtly different results is a key challenge for paleointensity studies, which often leaves interpretations of these data rife with ambiguities ...

Beryllium ten production and relative paleointensity for the past 1.2 million years
Quaternary Science ReviewsComposite curves of relative paleointensity document the evolution of the geomagnetic field intensity during the past 1.2 Million years. Several records of production of 10Be cosmogenic isotope from the 10Be/9Be ratio (referred to as Be-ratio) covering this period have also been acquired. We add here new 10Be records to the database and produce a first

Relative geomagnetic paleointensity across the Jaramillo Subchron and the Matuyama/Brunhes Boundary
Geophysical Research Letters, 1996 Analysis of old paleomagnetic data and new mineral magnetic data from a sediment core from the central equatorial Pacific Ocean indicates that this core can be used for determination of relative geomagnetic paleointensity. These data indicate that during the Jaramillo subchron, there was a gradual decrease in paleointensity from the onset of the ...

Long-teta VRM and relative paleointensity estimates in sediments
, 1999 Geomagnetic paleointensity measurements from sedimentary records can be severely affected by viscous remanent magnetization (VRM). We present a method for determining varying amounts of long-term VRM acquired during the present polarity interval, using the typically non-linear relationship between acquisition of artificial magnetization and ...

Geochemistry, Geophysics, Geosystems, 2021 Relative abundance of magnetite originated from magnetotactic bacteria (magnetofossils) in sediments may influence relative paleointensity (RPI) estimations of the geomagnetic field, as some studies reported an inverse correlation between RPI and the ...
