The kakortokites of the Mesoproterozoic Ilimaussaq complex, South Greenland, comprise a rhythmically layered series of agpaitic nepheline syenites that crystallized at the base of a shallow crustal magma chamber. They host eudialyte-group minerals (EGM), i.e. structurally complex Na-zirconosilicates...
