Dating agpaitic rocks:a multi-system (U/Pb, Sm/Nd, Rb/Sr and 40 Ar/ 39 Ar) isotopic study of layered nepheline syenites from the Ilímaussaq complex, Greenland
The Ilímaussaq complex in southern Greenland is a shallow crustal composite intrusion comprising augite syenite, peralkaline granite and volumetrically dominant agpaitic nepheline syenites. Previous studies indicated a baddeleyite U-Pb age of 1160 ± 5 Ma for the augite syenite, the earliest intrusiv...
