Cl isotope fractionation in magmatic and hydrothermal eudialyte, sodalite and tugtupite (Ilímaussaq intrusion, South Greenland)

We determined the Cl stable isotope composition of Cl-rich minerals (eudialyte, sodalite and tugtupite) from evolved peralkaline rocks of the Ilímaussaq complex (South Greenland) to determine the effects of orthomagmatic and hydrothermal processes on Cl isotope variations and to estimate the Cl isotopic composition of the lithospheric mantle source for the complex.
