GEOLOGICAL INTERPRETATION OF THE GRAVITATIONAL AND MAGNETIC FIELDS OF THE BALTIC SEA REGION.

Tectonic movements, which give form to the structure of the sedimentary deposits and to the relief of the crystalline basements internal structure, which, together with the relief and the depth of occurrence of its surface, is the chief factor influencing the nature of the gravitational and magnetic fields. The following problems are discussed in the translation a The structure of the gravitational field changes substantially, depending of the depth of occurrence, and on the relief of the crystalline basements surface. b If boundaries of the first-order tectonic structures are distinctly expressed in the crystalline basements relief in a form of faults of considerable amplitude, then their detection in the gravitational field is easy. The task becomes more complicated when the foundation is without gradients and its relief is smooth. c In order to determine the relation of the basements internal structure with its relief and with the structure of the sedimentary deposits, it is necessary to discover the differences in the basements internal structure within the boundaries of the different first-order tectonic structures. d Tracing the disjunctive dislocations in the crystalline basement can be solved by way of geological interpretation of the gravitational and magnetic fields.
