Brito-Arctic province

The Brito-Arctic province (also known as the North Atlantic Tertiary Volcanic Province) is a major flood basalt province of the North Atlantic Ocean. Basaltic volcanism flowed in two main pulses. The first which occurred ~61 million years ago was of 2 x 10⁶ km³ in total volume, into the current western and southeastern Greenland and northwestern Britain. The second and larger flood basalt flow occurred ~56 x 10⁶ years ago in both eastern Greenland and the Faroe Islands.^[1]
