The Mesoarchaean Akia terrane, West Greenland, revisited:new insights based on spatial integration of geophysics, field observation, geochemistry and geochronology

The northern part of the North Atlantic Craton (NAC) in southern West Greenland comprises a large tract of exposed Meso-Neoarchaean continental crust, divided into the ca 3300–2900 Ma Akia and ca 2900–2500 Ma Tuno terranes. We combine aeromagnetic, stream sediment geochemical, new litho-chemical and...
