Abstract

The continental shelf and slope of the Arctic seas contain many hydrocarbons and mineral deposits. An important object of shelf crust study is a Mohorovicic (Moho) discontinuity as a principle factor in formation of the structural and fault features. The paper considers the feasibility of gravimetry for studying inhomogeneities of the structure of the crust. On the basis of the VECTOR technology, a new technological scheme “Extension of gravitational anomal lower half-space, using seismic profile as a baseline” was developed and implemented. As a result, direct relationships between the anomalies of Δg and Moho depths were established. Conclusion about the feasibility of applying the transformations of the field in the VECTOR system for the study of the Earth’s crust on the shelf and continental transition zone was made.
