Senjen to Ringvasøi. 



As there are few detailed charts of the coast north of Vesterålen, it is 

 difficult to study the submerged strandfiat in this region, but on the 

 whole it seems to have very much the same character as along the outer 

 coast of Lofoten and Vesterålen. Outside the great island of Senjen 

 (where there is a detailed chart, Xo. Sj) the submerged platform is in 

 places as much as 9 kilometres broad, but has a very irregular much 

 dissected surface, with varying depth. The outer coast of this island is 

 also dissected by long, deep fjords. The rocks are to a great extent 

 granites. 



A submerged strandfiat of very much the same character as the one 

 just described to the south-west, extends along the outer coast north- 

 eastwards as far as Rebbenesoi, Grotoi, and northern Kvaloi (70° 16' 

 N. Lat.). In some places, e. g. outside southern Kvaløi, it attains a width 

 of 18 kilometres (in about 69" 55' X. Lat.). It is much dissected, and 

 carries a great number of scattered islets, skerries, and shoals. The coast 

 is supposed to be built up of igneous rocks similar to those of the coast 

 to the south-west. 



Finmarken. 



There are only few indications of a strandfiat. above or below 

 present sea-level, along the coasts east of the region of Ringvasøi, 

 northern Kvaloi, and \'annoi. This sudden disappearance of a fairlv 

 well developed strandfiat coincides in a striking manner with the sudden 

 change in the geological structure of the coast, as I have already mentioned 

 on pp. 50 f., where this fact has been discussed at some length. The lack 

 of detailed charts of this coast with sufficiently numerous soundings 

 prevents us from studying the detailed topography of its sea-bottom, and 

 of possible submerged platforms at deeper levels. 



In some places, e. g. on Sørøi (Fig. 122) where there are igneous 

 rocks (gabbro) I have observed indications of what mav be considered
