On improving the selection of Thellier-type paleointensity data [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2014
The selection of paleointensity data is a challenging, but essential step for establishing data reliability. There is, however, no consensus as to how best to quantify paleointensity data and which data selection processes are most effective.

Archeointensity estimates of a tenth-century kiln: first application of the Tsunakawa–Shaw paleointensity method to archeological relics [PDF]

open access: goldEarth, Planets and Space, 2018
Paleomagnetic information reconstructed from archeological materials can be utilized to estimate the archeological age of excavated relics, in addition to revealing the geomagnetic secular variation and core dynamics.

A paleointensity technique for multidomain igneous rocks [PDF]

open access: bronzeGeochemistry, Geophysics, Geosystems, 2013
We developed a paleointensity technique to account for concave‐up Arai diagrams due to multidomain (MD) contributions to determine unbiased paleointensities for 24 trial samples from site GA‐X in Pleistocene lavas from Floreana Island, Galapagos Archipelago.

Paleointensity.org: An Online, Open Source, Application for the Interpretation of Paleointensity Data

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Paleointensity.org is an online, open source, application to analyze paleointensity data produced by the most common paleointensity techniques. Our application currently supports four different methods: thermal Thellier (all variations), microwave ...

Paleointensity Determination Using the Thellier Technique

open access: bronzeJournal of geomagnetism and geoelectricity, 1986
The Thellier technique is discussed, specifically in respect of small (3×3mm) samples measured using a cryogenic magnetometer. It is concluded that as long as stringent criteria are imposed the technique gives reliable results. Agreement with the Shaw technique is noted, as also with observatory-based values.

Brunhes Paleomagnetic Directions and Paleointensities From Northern Hainan Island

open access: yesGeochemistry, Geophysics, Geosystems
Paleomagnetic studies typically assume that the long‐term, time‐averaged geomagnetic field behaves as a geocentric axial dipole (GAD). While paleodirectional data over the past five million years generally agree with GAD predictions, mid‐to‐low latitude ...

Determining Magnetic Field Intensity and Direction From the Anisotropy of Magnetic Remanence in Sediments

open access: yesGeochemistry, Geophysics, Geosystems
Anisotropy 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.

Thellier-type paleointensity data from multidomain specimens

open access: yesPhysics of the Earth and Planetary Interiors, 2015
Identifying and excluding inaccurate paleointensity estimates that can arise from the effects of multidomain (MD) particles remains a key challenge for paleointensity studies. Here we approach this problem by incorporating realistic experimental noise into a phenomenological MD model, systematically exploring the parameter space of paleointensity ...
