Southern Barents Sea Anomalous Magnetic Field and Its Correlation with Bottom Geological Structure

Abstract Results of data processing of marine magnetic surveys in a southern part of Barents Sea, executed from 1986 to 2001 are considered. The geomagnetic investigation of Southern Barents Sea bottom points on its complicated many-stage geologic-tectonic structures in which two disjunctive structures prevail: Riphean-Vendian inherited rift structures with north-west strike and orthogonal system of superposed faults transformed in north-eastern direction. Late Devonian alkaline intrusives with associated ore mineralization are confined to points of these systems intersection.
