Определение изменения плотности масс в горизонтальном слое по данным гравиметрии

The masses with an excess density <$E sigma~=~sigma (xi,~eta)> are located in horizontal layer. This layer is limited by two planes. The density is approximated by specially constructed functions complex. The gravity field on the ground surface is determined. An inverse gravity problem is led to minimization of constructed functionals. In case when we have several layers the problem can be generalized. Then datum points can be introduced. They permit to divide the masses into layers.
