Abstract

This review is based on compilations of dips, the distribution of amygdale minerals, and the intensity of the dyke swarms. These compilations enable the position of the original top of the crust to be deduced. The top lies generally well above the present summit levels, but is highest in the belt of country within which the highest summits occur. There is also a general rise southwards along the length of the belt to a maximum in the Quaternary volcanic district along the edge of the Vatnajokull. The non-parallelism of lava isochrons and dyke isochrons implies that there was a progressive southward shift in the zone of maximum spreading and probably a progressive intensification of activity as well.
