This granite is part of a large complex, composed predominantly of syenite, which forms the uninhabited island of Nunarssuit. The complex is the youngest in the Gardar period of rift-related alkaline magmatism, which extended from to Ma.

of rocks with a molar ratio of (Na + K)/Al ≥ 12 (61) and with complex Na–Ti–Zr silicates (49). Abstract. The Ilímaussaq complex in South Greenland is a well-studied multiphase alkaline to peralkaline intrusion of MesoProterozoic age.
Most of the Ilímaussaq rocks are extremely enriched in alkalis, iron, halogens, high-field-strength elements (HFSE) and other rare elements, forming one of the most differentiated peralkaline rock suites ://Magmatic pulses in the emplacement of plutons Magmatic pulses in the emplacement of plutons Harry, W.
