parallel to the serpentinos and soapstones of the area of Samn- 

 anger. As regards the eye-gneisses in Bergen we have correspon- 

 ding types in several of the gneisses of the Samnanger-area. 



A closer comparison between the inner and outer arch of the 

 Bergen-area will aceording to the knowledge we have now obtained 

 of these, give the result that both of them have consisted of approxi- 

 mately the same Silurian rocks; but that the rocks of the inner 

 arch has been more strongly compressed during the folding than 

 those of the outer one. The difference of metamorphism is, however, 

 onlya difference of degrees, and the alteration must in either case 

 have tåken place in the upper zone of the earth's crust under 

 circumstances where the one-sided pressure and the great amount 

 of water could put its stamp on the rocks.
