Summary:
At the present time, numerous methods of transformation have been developed that allow us to divide the gravitational field into components that are identified with the influence of various deep layers of rocks with a minimum of a priori information about the sources. The possibility of obtaining a three-dimensional picture of the field distribution in space makes these methods very attractive for geologists and geophysicists. Often geological interpretation of 3D images, the field is reduced to the application of the shear volume of models of fields contours, geological features or stratigraphic boundaries. This approach to the interpretation of the results of the tomographic transformation of the field is not completely valid. Only the use of methods of quantitative interpretation makes it possible to create a physical-geological model of the geological section from the 3D model of the field.
