A Review of the Glaciation Maximum Concept and the Deglaciation of Eyjafjördur, North Iceland

The Weichselian glaciation in North Iceland is divided into three main phases: (1) A maximum phase, characterized by merging outlet glaciers from local ice domes in Tröllaskagi with major ice streams from an inland ice sheet. These combined glaciers reached out to the shelf off North Iceland and overrode the island of Grímsey. (2) A phase characterized by repeated advances of the glaciers and the formation of several ice-dammed lakes in Fnjóskadalur. (3) A final phase which was denoted by an Alpine type of glaciation and the final departure of glaciers from the North Icelandic lowlands. A tephrochronological correlation has afforded a possible Younger Dryas age for the youngest icelakes in Fnjóskadalur. A14C date in Flateyjardalur has provided a minimum Preboreal age for the final déglaciation of the area and for the marine limit in Eyjafjörður.
