- Provincia Ígnea del Atlántico Norte
-
La Provincia Ígnea del Atlántico Norte o Provincia Ígnea Brito-Ártica es una gran provincia ígnea que se estima cubre un área de por le menos 1.3×106 km2 y cuyos productos tiene un volumen de 6.6×106 km3.[1] Geográficamente la Provincia Ígnea del Atlántico Norte compone la totalidad del norte del Océano Atlántico incluyendo basaltos Paleocenos y Eocenos de Groenlandia, Islandia, Reino Unido, Dinamarca, Noruega y muchas islas en el noreste del Atlántico.[2] [3]

The total crustal volume is 6.6×106 km3, resulting in a mean crustal accretion rate of 2.2 km3/yr. Thus NAVP ranks among the world's larger igneous provinces if the volcanic margins are considered.”
