| Summary: | The Sverdrup Basin is a sedimentary basin within the Canadian Arctic Islands. This area has had a complex tectonic and igneous history with several episodes of intrusive and extrusive activity. The last episode is believed to have occurred in two stages during the Cretaceous. The first stage resulted in the emplacement of dykes along a trend sub-parallel to the axis of the basin. The second produced a trend in a north-south direction and is believed to represent the landward continuation of the Alpha Ridge complex. The petrology and geochemistry of the north-trending swarm is examined and a brief comparison is made with the Strand Fiord Formation Volcanics. Keywords: Pages: 100 Supervisor: Gunter Muecke |
