Abstract

The numerical models and results of the gravimetric interpretation of the crustal density structures and the Moho geometry are presented. The numerical scheme applied utilizes the gravimetric forward and inverse modeling derived in a frequency domain. Methods for a spectral analysis and synthesis of the gravity and crustal structure models are applied in the gravimetric forward modeling of the gravity field generated by the major known crustal density structures. The gravimetric inversion scheme is formulated by means of a linearized Fredholm integral equation of the first kind. In numerical results we show the gravitational contributions of crustal density structures and the refined gravity field quantities, which have a minimum as well as maximum correlation with the Moho geometry. The resulting gravimetric Moho model is finally presented.
