EVOLUTION OF THE SOUTHERN PART OF THE CANADA BASIN (ARCTIC OCEAN) BASED ON MAGNETOMETRIC DATA

Abstract

Using a new Russian–American digital grid of anomalous magnetic field of the Arctic Ocean, oceanic magnetic anomalies were identified for the whole southern part of the Canada Basin (hereafter, southern CB), extending from the eastern scarp of the Northwind Ridge to the adjacent Banks Island–Mackenzie Delta continental margin. The geohistorical analysis of magnetic anomalies carried out based on the original procedure revealed regional features of the basin evolution. Contradictory ideas about this evolution were so far based on the geology of continental framing.
