A carbonatite-syenite intrusion between the Arsuk Fjord to the NW and the Ikka Fjord in the SE.

The Grønnedal-Íka alkaline complex of syenites and carbonatites is one of more than 10 intrusions formed during the breakup of the supercontinent Columbia, producing a rift system that extended across eastern Canada, southern Greenland, and beyond to Finland, measuring a distance of some 5000 km today. The Grønnedal-Íka complex of today has an elliptic shape of 8 × 2.8 km, which has been elongated from an original ovoid intrusion of 5.9 × 3.5 km through tectonically induced displacement and faulting. Carbonatites make up the core of the intrusion, surrounded by several rings of syenites of different chemical compositions. The following sequence for the formation of the Grønnedal-Íka igneous complex: An initial suite of layered nepheline syenites was intruded by late xenolithic porphyritic syenite and, finally, a central body of carbonatite was formed by explosively intruding into the still hot rock suites of syenites. The syenite rocks are divided into Lower and Upper Series), with the Lower Series being the oldest. The majority of the syenites in the Grønnedal-Íka complex are foid syenites. Xenolithic syenites intruded into the layered Lower and Upper Series at a later stage.
