The Balder Formation is a geological formation of lowermost Eocene in age, found in the Central and Northern North Sea and Faroe-Shetland Basin.[1] The formation is named after Balder, a god from Norse mythology. Layers of tuff are found, particularly at the base of the unit, deposited by airfall from volcanoes associated with the North Atlantic Igneous Province.[2]
