Figure 1. Map showing profile locations in the Arnarfjörður-Breiðafjörður area. All the profiles shown were
sampled in 2004–2008 except AB (Kristjánsson et al., 1975) and MH (unpublished). See Figure 2 for details.
The upper inset indicates the approximate positions of long composite stratigraphic/paleomagnetic sampling
sections in the peninsula, nos. 1 and 2 by McDougall et al. (1984), no. 3 by Kristjánsson and Jóhannesson
(1996) and no. 4 by Kristjánsson et al. (2003). Is = Ísafjarðardjúp fjord. F is the area on the Breiðafjörður
coast (Barðaströnd) mapped by Friedrich (1966). Asterisks indicate the approximate centers of eroded volcanic
complexes. – Kort af sýnasöfnunarstöðum milli Arnarfjarðar og Breiðafjarðar, 2004–2008. Á litla kortinu

research in the peninsula has however been rather spo-
radic, so that its overall stratigraphy is not yet well
known, especially north and east of Ísafjarðardjúp. In
the 18th and 19th centuries, and even to some extent
in the 20th century, the chief geological points of in-
terest in the area concerned the presence of lignite
and leaf impressions in unusually thick interbasaltic
sediments (cf. Friedrich, 1966; Kristjánsson, 1992;
Grímsson and Símonarson, 2008). They occur in sev-
eral locations, and some are assumed to belong to ex-
