On archeomagnetic secular variation curves and archeomagnetic dating

Physics of the Earth and Planetary Interiors, 2002
Abstract Secular variation (SV) of the Earth’s magnetic field can be used for dating purposes by comparing archeomagnetic directions of unknown ages with a well-dated reference curve. In this study, we propose a dating technique based on the statistics of McFadden and McElhinny [Geophys. J. Int.

New archeomagnetic and 226Ra-230Th dating of recent lavas for the Geological map of Etna volcano

Italian Journal of Geosciences, 2012
This work deals with the dating of Mount Etna lava flows and eruptive fissure deposits to the last four millennia following field investigations and stratigraphic data (BRANCA et alii, 2011a). We have studied 24 of these volcanic products, including 301 large samples, through high precision archeomagnetic dating checked by 226Ra-230Th radiochronology ...

Archeomagnetic dating of Mediterranean volcanics of the last 2100 years: validity and limits

Earth and Planetary Science Letters, 2003
Archeaeomagnetic dating developed at St. Maur laboratory has been applied to the Mediterranean volcanoes Etna, Vesuvius and Ischia. The method involves samples from lava flows or high temperature emplaced pyroclasts (welded scoriae, pumice, etc.) weighing 0.5-1 kg each, that allows reaching a precision of a few tenths of a degree on the direction of ...
