{{Short description|Late Cretaceous volcanic group in Ellesmere Island, Nunavut, Canada}} The '''Ellesmere Island Volcanics''' are a [[Late Cretaceous]] [[volcanic group]] of [[volcano]]es and [[lava]] flows in the [[Qikiqtaaluk Region]] of northern [[Ellesmere Island]], [[Nunavut]], Canada.
Ellesmere Island Volcanics are part of the [[Arctic Cordillera]]. This volcanic province is among the northernmost volcanism on [[Earth]].
== History == Even though these volcanics are about 90 million years old, the volcanoes and [[Scoria|cinder]] are still discernible.<ref>[http://www.earth.rochester.edu/pmag/arctic/arctic99/journalchris.html Chris's journal entries] {{Webarchive|url=https://web.archive.org/web/20060915132306/http://www.earth.rochester.edu/pmag/arctic/arctic99/journalchris.html |date=2006-09-15 }} Retrieved on 2007-08-05</ref> The volcanics of the Maskell Inlet Assemblage are mostly made up of [[tuff]]s, 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]].<ref>{{Cite journal|last1=Deegan|first1=F. M.|last2=Troll|first2=V. R.|last3=Bédard|first3=J.
