Bias Corrected Estimation of Paleointensity (BiCEP): An Improved Methodology for Obtaining Paleointensity Estimates [PDF]
Geochemistry, Geophysics, Geosystems, 2021 The assumptions of paleointensity experiments are violated in many natural and archeological materials, leading to Arai plots which do not appear linear and yield inaccurate paleointensity estimates, leading to bias in the result.

Deriving confidence in paleointensity estimates [PDF]
Geochemistry, Geophysics, Geosystems, 2010 Determining the strength of the ancient geomagnetic field (paleointensity) can be time consuming and can result in high data rejection rates. The current paleointensity database is therefore dominated by studies that contain only a small number of paleomagnetic samples (n).

ThellierCoolPy: A Cooling‐Rate Correction Tool for Paleointensity Data [PDF]
Geochemistry, Geophysics, Geosystems, 2021 We report a new approach of implementing cooling‐rate corrections in absolute ancient magnetic field intensity (paleointensity) studies. Nearly all methods of determining paleointensity estimates rely on rocks having recorded a thermoremanent ...

Comparison and Renormalization of Holocene Paleointensity Records From Central North America (17°N–51°N, 205°E–295°E) [PDF]
Earth and Space Science, 2021 This paper develops a composite absolute paleointensity record for Holocene paleomagnetic secular variation (PSV) from central North America. Twelve full‐vector (inclination, declination, paleointensity) PSV records were assessed in order to build the ...

New Paleointensity Data From Aniakchak Volcano, Alaska, USA
Geochemistry, Geophysics, Geosystems, 2021 This study presents the first set of Holocene, high‐quality absolute paleointensity data from Alaska, USA. Existing paleointensity data for the Holocene are generally located at mid‐northern latitudes in North America, Europe, the Middle East, and ...

Paleointensity Estimates From Ignimbrites: The Bishop Tuff Revisited
Geochemistry, Geophysics, Geosystems, 2018 Volcanic ash flow tuffs (ignimbrites) may contain single domain‐sized (titano) magnetite that should be good for recording geomagnetic field intensity, but due to their complex thermal histories also contain other magnetic grains, which can complicate ...

A multimethod paleointensity approach applied to the historical Xitle lava flows (Central Mexico): towards the accurate paleointensity determination [PDF]
Earth, Planets and Space, 2020 An inclusive rock-magnetic and absolute paleointensity survey of the ~ 2-ka-old Xitle volcano (southerly Basin of Mexico) was undertaken to assess the faithfulness of the paleomagnetic log carried by fresh, widely exposed and well-preserved lava flows ...

Paleointensity Database Updated and Upgraded [PDF]
Eos, 2010 The global absolute paleointensity (PINT) database, sponsored by the International Association of Geomagnetism and Aeronomy, recently was updated with new data and published alongside a new queryable interface at http://earth.liv.ac.uk/pint/.Absolute paleointensity determinations are spot readings of the strength of the geomagnetic field at the time ...

Geophysical Research LettersPaleointensity records are vital for understanding the Earth's evolution, but obtaining accurate paleointensity is a challenging task. The Shaw‐type method, a widely‐used paleointensity protocol, produces biased results occasionally despite strict ...
