The construction of the upper crust of the Yeletskiy section of LOsevskiy terrane (Voronezh crystalline massif) according to the density modeling data

Abstract

The paper considers the methods and results of geophysical study of the upper crust structures for the Yeletskiy site (northeast of the Voronezh crystal massif) on the basis of a complex of geological and geophysical data. The detailed 3D density model was built on the basis of an inversion of local gravitational field anomalies to the anomaly density values of the regional density lithosphere model of the East European Platform. The inversion procedure used data on the density of crystalline basement rocks and estimates of the thickness of these complexes. The results of the simulation demonstrate the possibilities of detailed density modeling to study the structure of geological complexes of the foundation. On the basis of the detailed model created, the possible spatial relationships of the main structural and rocks complexes of the upper crust of the study area are considered.
