The Grønnedal–Ika carbonatite–syenite complex, South Greenland: carbonatite formation by liquid immiscibility
The Grønnedal-Ika complex is dominated by layered nepheline syenites which were intruded by a xenolithic syenite and a central plug of calcite to calcite–siderite carbonatite. Aegirine–augite, alkali feldspar and nepheline are the major mineral phases in the syenites, along with rare calcite. Temper...
