Geology of Scandinavia, 299 



The phenomena of the stratification, the wavings of the beds, 

 the dislocations, the relation of their position to that of the 

 masses of eruptive rocks, may be studied more on a large scale, 

 and this study may raise new questions. 



6. Two great series of Dislocations in Scandinavia. — If we 

 cast our eyes over sufficiently detailed maps of Norway and 

 Sweden, we see pretty evidently that the principal features of 

 the eastern slope tend to two different directions whose com- 

 bination determines all the forms of the country. 



The first of these two directions, which is particularly per- 

 ceptible in the disposition of the isles of Loffoden, in that of 

 the arm of the sea, and of the lakes in the vicinity of Dron- 

 theim, and in that of the range called the Dovre Field, between 

 Drontheim and Christiania, runs N. E., and E. NE., cutting 

 the meridian of Christiania at an angle of a little above 60°. 

 It is at the same time cut at a very marked angle by the lar- 

 gest of the small chains of the Scandinavian Alps. The most 

 considerable of these chains, known by the name of Kiolen, 

 commencing at the north-eastern extremity of the Dovre Field, 

 separates Sweden from northern Norway ; and after dividing 

 at its north north-eastern extremity, among the different gulfs 

 of Finmack, it terminates in the Frozen Ocean at Sverholt, be- 

 tween Laxefiord and Porsangerfiord, and at Nord-Kyn, between 

 this last bay and Tannafiord. 



The existence of these two principal directions has led me 

 to conjecture that there must have been two principal series of 

 dislocations in Scandinavia ; the first of which would seem to 

 belong to the great system of dislocations which has affected 



tieth degree of latitude ; on the isle of Wyck, near the great isle of Sartaroe ; 

 and at Hope Holm, one league's distance from Bergen, near Tiosanger. 



A search for beds of dolomite in the mica-slate is also to be recommended. 

 *' There will be seen and found in them,'' say s^M. de Buch, •• many minerals 

 still unknown in these localities : green tourmalines, rubies, kyanites and 

 apatites. These dolomites are found at Casness, in the sixty-ninth degree of 

 latitude, where they are of great extent. They afterwards make their ap- 

 pearance on the isle of Seugen, in the environs of Kloiven, where the tremo- 

 lite is very beautiful ; at Lenwig, to the south of Tromstie, in the 69Jth de- 

 gree of latitude; at Benoejard, still nearer Tromsoe, with abundance of 

 Staurotide ; and lastly, on the isle of Tromsoe itself. These beds form a 

 great part of those mountains, and would very probably be found high up the 

 Fiords.
