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.

Bulk magnetic domain stability controls paleointensity fidelity [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2017 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 ...

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).

Geochemistry, Geophysics, Geosystems, 2022 Twenty‐two sites, subjected to an IZZI‐modified Thellier‐Thellier experiment and strict selection criteria, recover a paleomagnetic axial dipole moment (PADM) of 62.2 ± 30.6 ZAm2 in Northern Israel over the Pleistocene (0.012–2.58 Ma).

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 ...

The necessity of data availability in maintaining the value and longevity of paleointensity results [PDF]
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 ...

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 ...

Early Cretaceous absolute geomagnetic paleointensities from Córdoba province (Argentina) [PDF]
Earth, Planets and Space, 2006 We present here new paleointensity and geochronology results from Early Cretaceous volcanic rocks of Sierra Chica de Cordoba (Argentina). The new K-Ar isotopic ages of 5 samples range from 136 to 122 Ma.

Holocene Paleointensity of the Island of Hawai `i From Glassy Volcanics [PDF]
Geochemistry, Geophysics, Geosystems, 2018 This study presents new high‐quality paleointensity records and 14C radiocarbon age determinations from the Island of Hawai `i during the Holocene. Previous studies on Hawai `i use experimental methods and statistical selection criteria that may produce ...

Revised chronology for late Pleistocene Mono Lake sediments based on paleointensity correlation to the global reference curve [PDF]
, 2006 Lakes are highly sensitive recorders of climate processes, but are extremely difficult to correlate precisely to ice-core and marine records, especially in the absence of reliable radiocarbon dates. Relative paleointensity (RPI) of Earth's magnetic field
