Beskrivelse

The Archaean of South-East Greenland is a part of the North Atlantic craton and encompasses vast areas of agmatitic gneiss and alkaline intrusions in the Skjoldungen Alkaline Province. Alkaline rocks are otherwise absent from the North Atlantic craton in Greenland and many other Archaean cratons elsewhere. The geology has been reinterpreted based on new field data, petrology, and whole rock geochemistry gathered during the 2009 field season of the mineral resource assessment programme – MRAPSEG.
