Zircon REE-profiles. A to F: all analyses. The data have been filtered using the Light Rare Earth Element Index LREEI = (Dy/Nd) + (Dy/Sm) alike Bell et al. (2019). A, caption for B to F with: 1: LREEI < 40, altered zircon. 2: LREEI > 40, valid zircon chemistry. Only valid data (C to F) have been further used, excluding Clefcy zircon data (B). G: reference profiles according to plate tectonics context (Grimes et al., 2015, to which missing Pr values were added stating (Nd/Pr)N = 2.2, based on the average of our valid zircon profiles). H: reference profiles according to host rock-types (Belousova et al., 2002). I to L, valid zircon profiles from our dated rocks, with grey background showing the range of the reference profiles G, and dotted lines for H profiles, respectively.
