Comment:
Calculation of Nd model ages and epsilonNd values are based on 143Nd/144Nd = 0.512638 and 147Sm/144Nd = 0.1967 for the chondritic uniform reservoir (CHUR, Jacobsen & Wasserburg 1980, doi:10.1016/0012-821X(80)90125-9), and 143Nd/144Nd = 0.513114 and 147Sm/144Nd = 0.222 for depleted mantle composition (Michard et al. 1985, doi:10.1016/0016-7037(85)90051-1).
