TL;DR: A 250m thick volcanic sequence of some 63 Pliocene lava flows from Georgia (Akhalkalaki plateau) which was previously thought to record the Gauss-Matuyama reversal was re-studied in detail as discussed by the authors.

Paleomagnetic volcanic data and geometric regularity of reversals and excursions
TL;DR: In this article, the authors examined a paleomagnetic lava database covering reversals and excursions which have occurred over the last 20 Myr and found that volcanic data give intermediate virtual geomagnetic poles (VGPs) which tend to fall along American and Asian longitudes, roughly consistent with the sedimentary data.

Geochronology of Pliocene volcanism in the Dzhavakheti Highland (the Lesser Caucasus). Part 1: Western part of the Dzhavakheti Highland
TL;DR: In this article, an isotopic-geochronological study of the Pliocene magmatic activity in western part of the Dzhavakheti Highland (northwestern region of the Lesser Caucasus) is carried out.

Palaeomagnetic secular variation as a function of intensity
TL;DR: In this article, the authors examined a database consisting of magnetic field data and found that the rate at which the magnetic field is changing in time is a function of the field strength.

The least-squares line and plane and the analysis of palaeomagnetic data
TL;DR: In this paper, principal component analysis is used to find and estimate the directions of lines and planes of best least squares fit along the demagnetization path of a palaeomagnetic specimen.

A new geomagnetic polarity time scale for the Late Cretaceous and Cenozoic
Steven C. Cande,Dennis V. Kent +1 more
TL;DR: In this article, the relative widths of the magnetic polarity intervals for the entire Late Cretaceous and Cenozoic have been systematically determined from magnetic profiles from the world's ocean basins.
Geomagnetic paleointensities from radiocarbon‐dated lava flows on Hawaii and the question of the Pacific nondipole low
TL;DR: In this paper, the ages of basaltic lava flows on the island of Hawaii were investigated using the Thelliers' method in vacuum and the results showed that the dispersion of virtual geomagnetic poles for the eight lavas is 15.5°, appreciably larger than the average for older lava flows.
