| Summary: | The research area, which is rectangular in shape and stretches from the 69th parallel to the Arctic Ocean, is divided into multi-stage square units. Morphometric analyses have been made of the certain components of the landforms within these units. On the basis of the distribution of these components it has been possible to draw some conclusions concerning the morphogenesis of Northern Lapland which do not fully correspond to those made earlier. The bipartite division which is distinguished in the relief is the result of different erosional processes caused by climatic changes rather than a consequence of different stages of evolution caused by similar erosional processes. In the same way it seems that the theory of superposition and inheritance explains more convincingly the interrelations between the elements of relief than the theory of local accelerations of fluvial incision caused by very late block movements. On the basis of the arguments used in the paper, the glacial transformation of earlier landforms in the Finnish part of the research area may be regarded in general as having been slight and in places almost nonexistent. Thus also the tor-like forms belonging to the minor relief have been able to a certain extent to escape ultimate destruction during the latest glaciation. (Author) |
