TECTONIC SETTING AND GEODYNAMIC NATURE OF THE SAINT ANNA TROUGH (NORTHERN BARENTS-KARA CONTINENTAL MARGIN)

Abstract

he present paper is based on the geotectonic interpretation of marine geological–geographical data with consideration of publications devoted to paleomagnetic investigations and isotope datings of rocks from the adjacent land and islands. We assume that the Saint Anna trough is a boundary structure located between the Svalbard and Kara plates. The consequent geodynamic implications of its origin are also discussed.
