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.

Key words:  marine magnetic surveys; Barents Sea; geologictectonic structure
