Paleomagnetic studies in Skarðsheiði, SW-Iceland
Table 1. Paleomagnetic results from new sampling profiles in Skarðsheiði and three flows in Akrafjall. N, num-
ber of samples used in calculation of best mean field. DEC and INC, declination and inclination of best mean
field after tectonic tilt correction. LON and LAT, coordinates of virtual pole corresponding to this direction.
ALF, 95% confidence angle for the best mean direction degrees, (in brackets if N=2). J100, arithmetic average
remanence intensity after 10 mT AF treatment (in brackets if affected by lightning), A/m. POL, paleomagnetic
polarity (N if lat > 0, R if lat < 0, T if the numerical value of lat < 40, E if the numerical value of lat < 10).
– Lava, númer hraunlags, N fjöldi sýna; DEC og INC meðalsegulstefna eftir hallaleiðréttingu; LON og LAT
hnit sýndarsegulskauts, ALF óvissa í segulstefnu, J100 meðalstyrkur segulmögnunar, POL er N fyrir „rétta“
segulmögnun, R fyrir „öfuga“, T og E tákna að segulskautið sé nálægt miðbaug.
