Supplementary data to: Compositional variations in the rinkite-(Ce)-nacareniobsite-(Ce) solid solution provide evidence for fractionation processes in highly peralkaline magmas (Ilímaussaq Complex, South Greenland)

The attached Excel file provide compositional data produced by electron microprobe analyses of rinkite-(Ce), nacareniobsite-(Ce), clinopyroxene and amphibole from the Ilímaussaq complex, South Greenland. The analytical methods and sample descriptions are available in Skursch et al. (2025), please cite that reference for use of data (see related material).
