Title: Crustal movements and geodynamics in Fennoscandia
Abstract: The Fennoscandian shield — the classical area of glacial isostasy — has been subjected to a complex sequence of motions throughout the Late Cenozoic. Still the geometry of the areas deformed has been roughly the same. An asthenosphere of low viscosity (1020–1021 poises) and a lithosphere of high flexural rigidity are established. The present uplift represents an other mechanism than the rapid glacial isostatic readjustment of the low-viscosity asthenosphere and seems to originate from mesospheric motions. At around 1900–1910 there was a distinct geodynamic change which seems to be controlled by changes in the Earth's rate of rotation. The postglacial uplift of Fennoscandia is found to be associated with intensive neotectonism: faulting, fracturing and seismicity.
