Kvamshestens devonfelt. 85 



map of the district between the two well-known Norwegian fjords, 

 the Sognefjord and the Nordfjord (fig. 39). On the map the 

 Devonian area of Sulen is marked by S, that of Bulandet and 

 Værlandet by B, that of Kvamshesten by K, that of Haasteinen 

 by Haa and that of Hornelen by H. H is put at the place, where 

 the famous mountain Hornelen is. 



The rocks below the Devonian area of Kvamshesten. 



On the geological map PI. I we find in the northern and 

 southern parts granites and gneisses which hitherto have been 

 considered as belonging to the Archean. 



Between these rocks and the Devonian area there are zones 

 of phyllites, quartzites, greenschists and mangerite syenite. 



Although no fossils have been found in the phyllites which 

 are rich in mica, it is most likely that they belong to the phyllite 

 division which we find in the Stavanger district, in Hordaland and 

 in the Trondhjem district. The age is Cambrian and old Ordovician. 



The green schists I think we must compare with the green 

 schist division in the districts mentioned above, in the Trondhjem 

 district by Carstens called the Bymark group. 



The quartzites and quartzschists, which partly have been worked 

 as roofing slates, are perhaps the equivalents of the quartzschists in 

 the Voss district and in the mountains in the central part of southern 

 Norway, but this is rather uncertain. 



The mangerite syenite which shows rather considerable dif- 

 ferentiation is a Caledonian igneous rock. 



Above these rocks we find the area of Kvamshesten with its 

 Devonian breccias, conglomerates and sandstones. 



Some general remarks on the Devonian area of Kvamshesten. 



The area of Devonian conglomerates and sandstones forms 

 a naked mountain district with no farms and is at many places 

 separated from the lower land by steep mountain sides. The 

 highest points are Bleien 1318 m., Kvamshesten 1239 m., Lille- 

 hesten 901 m., Eidsfjeld 809 m., and Løkelandshesten 802 m. 

 Some of the steep mountain sides on the southern border may 

 be seen at fig. 1.
