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.

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.

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 ...

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 ...

Paleointensity behavior in Barremian–Cenomanian (Cretaceous)
International Journal of Geomagnetism and Aeronomy, 2004Fragmentary knowledge on geomagnetic field intensity in Barremian–Cenomanian stageobtained from sediment rocks is summarized. Three types of periodical variations arerevealed in the paleointensity behavior. The types differ by the amplitude and duration(tens of millennia, hundreds of millennia and more than million years).

Interactions in rocks and the reliability of paleointensity data
Earth and Planetary Science Letters, 1969Abstract A simple theory of thermoremanent magnetization (TRM) of magnetostatically interacting single-domain grains is presented in this paper. In first approximation, small-field TRM is proportional to applied field and inversely proportional to mean interaction field,Hi.
