1914—15] Fjeldbygiringen mellem Sørfjorden og Samnangerfjorden. 219 



East of this gneiss-zone is a narrow series of rocks consisting 

 of marble and phyllite, wbich, due to several faults in the direction 

 from east to west, is not continuous. Still farther to the south 

 in the narrow isthmus at Liøen, we find a small zone of marble 

 which must be considered as a continuation of the series just 

 mentioned. 



East of this zone again we tind a still larger area of polymict 

 conglomerate, which is intersected by pressed granitte rocks of 

 greyish colour. This rock makes a striking contrast to the neigli- 

 bouring rocks by the scarcety of vegetation. To the east of the 

 conglomerate we first meet a narrow granitte zone and then a 

 somewhat larger one of greenschists and similar rocks. The grea- 

 test portion of the central area of the map is occupied by a zone 

 of phyllites, where also various gneissose rocks occur together with 

 different kinds of serpentines and soapstones; finally there is a zone 

 of saussurite-gabbros in the tract east of Aldal. 



East of the above zones is a belt of saussurite-diabase-schists. 

 zoisite-hornblende-schists and similar, and still east of the latter is 

 an area of labradorite-rocks which contain smaller portions of closely 

 related rocks, as for instance, mangerites, birkremites, norytes and 

 pyroxenites, which I have not marked on the map. Finally on the 

 northern stretch towards Vaksdal the above rocks are followed 

 by Archæan gneisses into which several phyllite-zones are pressed. 



The Saussurite- Gabbros and Pressed Granites of 

 Gulfjeldet. 



(Pages 17-36.) 



During his journeys in Norway at the beginning of the last 

 century Cael Feiedeich Naumann also made some excursions in the 

 tract of Gulfjeldet, and in his work, "Beytrage zur Kenntnisz Nor- 

 wegens", he has given some information concerning the structure 

 of the saussurite-gabbros, which may still be read with interest. 

 Naumanirw^as also observant of the two large dykes of granulite 

 in the steep mountain-walls of the Gulfjeld-bottom. An analysis 

 of this dyke-rock has subsequently been made by Hioetdahl and 

 Tegens for their paper "Geologiske undersøkelser i Bergens omegn" 

 ("Geological investigations in the environs of Bergen"). The result 

 of this analysis is quoted on page 10 of the present paper.
