Аннотация:Postglacial rebound velocities of the Baltic Shield are estimated from data obtained within the framework of international and Russian GPS projects. An anomalous value of the velocity is obtained in the Lake Ladoga area, and a geological-geophysical interpretation of this anomaly is given. The GPS estimates of postglacial rebound velocities are used for preliminary estimation of the upper mantle viscosity under Fennoscandia. On a first approximation, the relation between the amplitude of isostatic gravity anomalies and velocities of vertical movements is studied.
