VERTICAL MOVEMENTS OF THE CRUST, VARIATIONS OF THE GRAVITY FIELD WITH TIME, AND MOVEMENT OF SUBCRUSTAL MATERIAL,

Abstract : The paper discusses the correlations between the gravitational field and the vertical crustal movements and the displacements of material along the earth's surface. The regions of stable platforms, highly mobile regions and areas of modern glaciation are described. The paper shows how the vertical crustal movements are followed by subcrustal horizontal dislocations of the matter. A suggestion is made that the main cause for the vertical crustal movements on the platforms lies in the changes of the volume of matter under the crust and in the lower layers of the crust. (Author)
