I92I. Xn. II. THE STRAXDFLAT AND ISOSTASV. 25I 



where the upper limit of submergence lies no higher than the strandflat, 

 more detailed investigations would probably demonstrate a horizontal 

 upheaval of the outer coastal region, and a tilted upheaval of the land 

 inside, in quite a similar manner as we have found in the region of 

 Xord Fiord. 



Gradient of the Lateglacial and Postglaciel Upheaval of the West 

 and North Coast of Fenno-Scandia. 



A general impression of tlie postglacial upheaval of the land may be 

 obtained by comparing the gradients of this upheaval in the different 

 regions of the coast of Xorway and of the Kola Peninsula as given in the 

 following table. The values of the gradients are computed from the heights 

 of the highest terraces and raised beaches which are supposed to indicate 

 the upper limit of lateglacial submergence. The heights were measured 

 by the authors given in the last column. The heights of the lower leve! 

 of the strandflat have not been deducted from the figures used for the 

 computation of these values. 



In several regions it is difficult to decide which raised terraces and 

 beaches actually indicate the upper limit of lateglacial submergence. In 

 the outer coastal regions of Finmark Tanner [1906, 1907] has found 

 raised shore-lines and terraces situated considerably higher than those 

 which have been used for the computation of the gradients in our table. 

 Similar higher shore-lines have also been found at several levels bv 

 Gronlie [19 14" in the Tromso distrikt and by W. Ramsay [1898" on the 

 Kola Peninsula. These shore-lines, however, are less distinct than the 

 lower shore-lines and have a much older appearance. Thev do not seem 

 to correspond to the shore-lines which are supposed to mark the upper 

 marine limit (the upper limit of lateglacial submergence) further south 

 in Xorway. and it is difficult to understand that they can have been 

 formed during the last glacial period. They may more probablv be sur- 

 vivals from a previous period of submergence, as is assumed by Ramsay 

 and Gronlie. 



For my computations I have therefore used the heights of the shore- 

 lines and terraces belonging to the level which Tanner calls le, as this 

 level seems to correspond to the upper level of the two conspicuous raised 

 shore-lines of the Tromso — Hammerfest region and \'esterålen. and to 

 the generally accepted upper limit of the lateglacial submergence farther 

 south in Xorwav. 



These gradients given in the table differ so much locally that one 

 might doubt their correctness; but on the whole there seems to be a certain 

 system in their variations. If they be introduced in a map of the Xor- 

 wegian coast where the submerged continental shelf is also outlined [cf.
