A preliminary note on some peridotites from Northern Norway.
The region shown on the map, fig. 1 was visited by the writer in the summers of 1952 and 1954. It is situated south of Bodø, just north of the polar circle.
Fig. 1 has been based on the maps of Rekstad (3) and G. Holmsen (1) and in a smaller area on observations made by S. Skjeseth and the writer. It shows the granitic areas and the known occurrences of peridotite. As to the last-named rocks the observations of Rekstad and Holmsen are incomplete; therefore fig. 1 contains a few more occurences than indicated on the older maps, but it is the writers conviction that there may still be found many more occurrences of peridotite in this region.
