Summary
The present geological map has been prepared on the basis of the official topographical map Fokstua-Kongsvoll, and upon a study of air photos provided by Folldal Verk mining Co. The air photos, scale ca. 1:10 000, are the series N grader 901 by Widerø's Flyselskap and Norsk Polarfly, Oslo. The interpretations have been checked in the field during several days' field study.

Summary
A three-phase conceptual glacial geological model for the Late Pliocene and entire Pleistocene period has been developed. The model explains variations in erosion in the Barents Sea in space and time and shows:
The first phase (until ca. 1.5mill. years) was characterized by glacial erosion over the present land areas of Svalbard and Norway. Minimal, if any, erosion over present shelf areas.
A transition phase (ca. 1.5 - ca. 0.5 mill. years) with glacial erosion over restricted areas. In the Norwegian sector glacial erosion was active from Svalbard down to the Bear Island Trough. Little, if any, glacial erosion south of the Bear Island Trough.
The last phase (ca. 0.5 mill. years - present) is characterized by glaciations covering the entire shelf areas. This seems to be the only period when repeated glaciations eroded in the southwestern Barents Sea shelf, i.e. in the areas of petroleum prospecting.
The three-phase glacial erosion model is supported by data on climate change over the period, by modelled change in topography, and by glacial geological data, especially from the Barents Sea. The approach and data also show that there is a great potential to test and refine the model to make it applicable to erosion estimates.

Summary
(Forkortet)
The geology of the Lofoten region has been described with the aim of assessing whether or not the area would qualify as a candidate for the World Heritage List based on its natural properties.
The Lofoten archipelago consists mainly of Palaeoproterozoic rocks, including paragneisses and younger plutons (ca 1800 Ma) of the anorthosite-mangerite-charnokite-granite (AMCG) suite. The Precambiran basement of the Lofoten and the adjoining Vesterålen islands is part of a NNE-trending basement high that is overlain to the east by a stack of allochthonous nappes occupying the central axis of the Scandinavian Caledonides.
