Ellesmere Island Volcanics
- Ellesmere Island Volcanics
The Ellesmere Island Volcanics are a Late Cretaceous group of volcanoes and lavas in the Qikiqtaaluk Region of northern Ellesmere Island, Nunavut, Canada. It is part of the Arctic Cordillera and is among the northernmost volcanism on Earth. Even though these volcanics are about 90 million years old, the volcanoes and cinder are still able to be seen. [ [http://www.earth.rochester.edu/pmag/arctic/arctic99/journalchris.html Chris's journal entries] Retrieved on 2007-08-05] The volcanics of the Maskell Inlet Assemblage are mostly made up of tuffs, with smaller flows. Compositionally these are mostly andesite or undifferentiated andesite/basalt. The volcanics on Ellesmere Island has been uncertainly associated to both the early volcanic activity of the Iceland hotspot and the Alpha Ridge. The Ellesmere Island Volcanics are part of the High Arctic Large Igneous Province.
