Paleomagnetic studies, Northwest Iceland
Table 1. Paleomagnetic directions and virtual pole positions in Northwest Iceland profiles sampled in
2010–2012. n = number of samples used in averaging. Dec, Inc = declination and inclination of primary
remanence direction after tectonic tilt correction. Lon, Lat = east longitude and north latitude of pole. Alf =
95% confidence angle for the mean direction, degrees. J10 = arithmetic average remanence intensity after 10
mT AF treatment, A/m. Pol = polarity: N = normal, R = reverse, T = transitional (Lat. between 10◦ and 40◦),
E = equatorial (Lat. below 10◦). – Segulstefnur, staðsetningar sýndarsegulskauta, og styrkur segulmögnunar
sýna úr jarðlagasniðum.
