This paper concerns palaeomagnetic studies of 10 lava sequences in southwestern Iceland. The sequences contain 329 lavas. Specimens which have been A. F. demagnetized provide palaeomagnetic polarities which agree very well with Tr. Einarsson's earlier compass studies of the same sequences in the field. Little new information is provided about the stratigraphic correlations among the various sequences investigated. Interpretation still depends essentially on Einarsson's original field mapping. Mean N and R pole positions are not significantly different, but are both on that side of the geographic pole far from Iceland, which conforms with the world-wide pattern recently emerging. Three transition zones provide new evidence about the behaviour of the geomagnetic field during inversion of polarity.
