THE STRANDFI.AT AND ISOSTASV

Hi the hill above Glesvaer harbour. lAug. 21, 1901.1 



It is interesting" to note that tlie strandtlat in this region just north 

 of Glesvær and across th.e land westwards is cut in flioritic rocks, while 

 the land both north and south, on Store Sotra and the other islands, is 

 built up of Archæan gneiss and partly of granite [Reusch, 1901, p. 106]. 

 This n^.akes apparantly no difference in the height of the level strandfiat. 



Islands between Kors Fjord and Hardanger Fjord. 



South of Kors Fjord (Fig. 21, no. 83) I observed a distinct strand- 

 flat extending over the southern parts of Hundevàgoi (granites), and over 

 Horge Island (granites) along the eastern side of Hufteroi (granites), and 

 on the small islands to the west of the latter: Mogster Island (schists and 

 ether rocks), the Aker Islands (where it is very conspicuous). Fugloi 

 (gabbro), and the many surrovmding islets. 



On the southern side of Hufteroi the strandfiat is sharply incised in 

 the mountain slope consisting of gabbro. 



Along the southern side of Selbjorn Fjord a well developed strand- 

 flat, al)out 30 metres above sea-level, extends from Slotteroi Lighthouse 

 over all the islands eastwards as far as the western side of Fondoi. These 

 islands consist of granites, while the eastern part of Fondoi consists of 

 gabbro. 



On l)oth sides of Langenuen Sound a strandfiat is well marked, on 

 the northern end of Stord Island (gabbro) as well as along the south- 

 western side of Reksteren Island (granites) and along the west side of 

 Tysnes Island (gabbro), see Fig. 60. 



Along the western side of Stord Island the strandtlat is distinctly 

 defined, but at an altitude perhaps somewhat higher than the usual level 

 of the strandfiat. The rocks are here granites, and in the southern part 

 chlorite schists or similar schists, and also some conglomerate. 



Along the eastern side of Stord Island there is a -fairly distinct, but 

 relati\'ely high strandfiat on many points, especially in the southern part 

 near I-eirvik (Fig. 61). The rocks are phyllite anrl in the northern part
