To investigate cumulus and post-cumulus processes within layered igneous intrusions we collected cross-polarised thin section images and electron backscatter diffraction (EBSD) data from the layered nepheline syenites (locally referred to as kakortokites) at Ilimaussaq, South Greenland. EBSD was completed at the University of Leeds on a FEI Quanta 650 FEG-ESEM with AZtec software and an Oxford Symmetry EBSD detector. Energy dispersive spectroscopy (EDS) data was collected to confirm the mineral phases identified by EBSD and to assess any zoning within the minerals.
