Purpose. <\/strong>In solving geological-geophysical mapping problems, wide use has recently been made of a block-layered structure model with inclusions of no hierarchic structure. For these models, devices and methods were designed to investigate 3D heterogeneous medium applying a theory suggested for geophysical data interpretation. A significant result of the previous century was a conclusion regarding the important role of a block hierarchic structure of rocks and missives in explaining the existence of a wide set of nonlinear geomechanical effects, and the appearance of complicated self-organizing geo systems in analyzing large and super large deposit formations. The hierarchic structure is characteristic of many systems, especially for the Earth\u2019s lithosphere, for which more than 30 hierarchic levels have been identified based on geophysical information. Thus in constructing new complex systems for geophysical investigation of the Earth\u2019s lithosphere this importation should be taken into account.
\nMethods. <\/strong>We constructed iteration algorithms for 2D<\/em> modeling of sound wave diffraction and linear polarized transversal elastic wave on an inclusion with hierarchic elastic, located in the J<\/em>-th layer of the N<\/em>-layered elastic medium. We considered a case where the density of the inclusion of each rank differs from the density of the surrounded layer and the elastic parameters are equal to the elastic parameters of the surrounded layer. We used the method of integral and integral-differential equations for space frequency representation of the wave field distribution.
\nFindings. <\/strong>From the suggested theory it is evident that integrating seismic and gravitation fields it is necessary to use the data obtained by the systems of observation that are set to observe the medium hierarchical structure. The application of the density values, derived from the correlation dependence between the velocity values of the longitudinal wave obtained from the kinematic interpretation of seismic data, and the density, for constructing a density model based on gravitational data, can lead to a discrepancy of the obtained model and the matter content of the investigated geological medium.
\nPractical value\/implications. <\/strong>These results may be useful in constructing new mapping systems of geological systems. They are especially significant in mapping oil and gas deposits and in forecasting their efficacy.<\/p>\n
