Summary:Early Precambrian basic rocks in Greenland and Scotland comprise suites with a wide range of ages, compositions and metamorphic grade, and include plutonic, hypabyssal and volcanic types. The two provinces are conventionally considered to have been originally part of the same craton, and contiguous with the Nain Province of eastern Labrador before the opening of the North Atlantic. The Archaean craton from SW Greenland to the Lewisian of Scotland comprises a high-grade gneiss complex. The topics discussed include: age and distribution of the basic rocks, early Archaean volcanism, the Isua-Akilia association, mid-Archaean basic magmatism, early Proterozoic basic magmatism and basic magmatic evolution and crustal growth in the North Atlantic craton.
