Fra Hardangervidden II

Abstract

Forkortet: The present author has chiefly worked in the middle part of the district. The sections on p.37 show granitic rocks that have been pushed over the Cambro- Silurian phyllite along thrust-planes. The picture on p.36 is from a mountain consisting of granite in its upper part and of phyllite underneath. The moun- tain on p.39 is of another kind, as the hard rock there is bluish quartzite, which is itself a link in the Cambro-silurian series. A section of the same mountain is represented by the figures a and b on p.40. The small section on p.41 is from a locality where a valley has been formed along a fault line. The picture above, fig.8, shows the aspect of the same locality as it is in the nature. Fig.13 illustrates a very crumpled quartzite. The diagram on p.48 from a locality where the Cambro-Silurian phyllite occurs in contact with Algonkian schistose gabbro and conglomerate. The glacial striation runs in a direction between W and NW in the higher parts of the region, while in the lower parts it is very much affected by the trends of the valleys.
