Multivectorial paleointensity determination by the Thellier method
Journal of Geophysical Research: Solid Earth, 2006Theoretical and experimental study of shape of the Arai‐Nagata diagrams for the natural remanent magnetization (NRM) consisting of two low‐ and high‐temperature partial thermal remanent magnetization vectors directed at angle θ to each other is considered.

Geomagnetic Paleointensity Around 30 Ma Estimated From Afro‐Arabian Large Igneous Province
Geochemistry Geophysics Geosystems, 2020We conducted a geomagnetic paleointensity study of lava flows at ∼30 Ma distributed in the Lima‐Limo section of the Afro‐Arabian Large Igneous Province.

A review of lunar paleointensity data
Advances in Space Research, 1982Abstract An extension of the saturation remanence normalization method to over 50 samples implies that a lunar surface field, comparable in intensity to the Earth's magnetic field, existed from about 3.65 to 3.85 AE. Absolute paleointensity estimates published to date, and surface field strengths, as measured by the Apollo subsatellites, are in ...

The inverse problem of paleointensity determination
Physics of the Earth and Planetary Interiors, 2004Abstract Analysis of paleointensity experimental data is often carried out using a special simple case of error-in-variable (EIV) formalism. Though mathematically sound, this approach is quite limited in the ways it offers to assess uncertainty and quality of the paleointensity estimates.

Paleointensity determination by a modified thellier method
Physics of the Earth and Planetary Interiors, 1977Abstract It has been frequently observed that the ferromagnetic minerals in volcanic rocks may undergo some physical/chemical changes when they are heated in a laboratory. For paleointensity determinations, it is therefore desirable to use the Thellier method, in which internal consistency of the data assures that such undesirable changes did not ...

Paleointensity across the Réunion event in Ethiopia
Earth and Planetary Science Letters, 1999Abstract Paleointensity experiments have been conducted on a volcanic series of 33 flows which recorded the geomagnetic Reunion event. Successive determinations of absolute paleointensity from 20 flows indicate that the Reunion event would actually be characterized by two successive periods of low field intensity, with a total duration not in excess ...

We study seven out of the thirteen lava flows associated to El Metate shield volcano using paleomagnetic, absolute intensity and rock-magnetic experiments. Characteristic paleomagnetic directions were successfully determined from most of the flows.

Harmonic fluctuations in the relative paleointensity data?
2021<p>The existing relative paleointensity (RPI) database allowed the construction of reliable stacking curves for at least the last 1 Myr. Observed fluctuations in the RPI curves suggest both lithologic/climatic influence or geodynamo processes.

The A.R.M. correction method of paleointensity determination
Earth and Planetary Science Letters, 1978Abstract A new method has been developed for recovering paleointensities from igneous rocks which requires only a single heating to the Curie temperature, utilizing partial ARM acquisition measurements before and after the heating to carefully separate distortions of the coercivity spectrum, caused by the heating, from viscous components present in ...
