Geological-geophysical models of the crust for the White Sea region

The study of the White Sea region and the adjacent area aimed to model the structure of the crystalline portion of the crust at the contact of the northeastern slope of the Fennoscandian Shield and the Russian Plate. Modeling was based on geological, geophysical and DSS profile data, State Geological Map of the Russian Federation (scale 1:1 000 000), Explanatory Notes to Sheets Q-35, 36, 37, and 38 (third generation, 2009), and Tectonic Map of the White Sea and Adjacent Areas (2012). A model was constructed using GIS INTEGRO software (VNIIgeosystems), specifically its procedures for calculation and visualization of 2D and 3D models showing crust density and magnetic fields. The model of the study area shows the structure of the crust and the characteristics of its horizons.
