We offer two approaches for construction of block lithosphere models. First is for selection of blocks in mantle only, it is applicable to both two- and three-dimensial models. Second method (3D) helps to select blocks related to known tectonic structures. Usual approach for tectonic maps construction is the gravity field analysis. However, this method is significantly limited because the gravity field includes integral information about density features in lithosphere. This makes impossible to split selected tect...

Geophysical data interpretation methods are very important for the study of the EarthпїЅs internal structure and gas and oil exploration. In this paper we offer a method to interpret gravity anomalies (identification of the local density of inhomogeneities) based on new grid algorithms: a three dimensional density distribution is constructed as grid functions by identified anomalies from the sources split along horizontal layers. Algorithm is based on new grid techniques of 3D gravity inversion. The initial approx...
