386 Karl Pettersen — Geology of N. Norway. 



Keilhau has given the result of his inquiries in his well-known 

 work : " Goea norvegica, 2 volumes, Christiania, 1844." 



More connected geological examinations of these countries were 

 commenced in 1865, and have been continued, but are still far from 

 being concluded. During this time Mr. Tellef Dahll has gone over 

 East Finmark and the inland of West Finmark, and the author of 

 these pages over the coast-land of West Finmark, the whole of 

 Tromso Amt, and the greater part of Lofoten and Vesteraalen in 

 Nordlands Amt. 



A more detailed description of the course and results of the 

 investigations will be found in the following treatises :

 In the following pages we shall try to give a concise view of the re- 

 sults gained through the researches instituted up to the present time. 

 In the districts (Amts) of Finmark and Tromso, and in the 

 shrieval districts (Fogderier) of Lofoten and Vesteraalen in the 

 district (Amt) of Nordland, there occur from below upward the 

 following stratified groups : 



I. The primitive rock. — This appears as narrow or wider stripes 

 in the coast-tract Island-group from Magero towards the north, to 

 the termination of Lofoten in the south. It forms moreover the 

 northern part of the peninsula which projects between Alten and
