Fig. 3.
Comparison between the numerical results obtained from Eq. 3 and the experimental data (i.e., the peak δD values reported in Fig. 2 at +180‰, +520‰, +980‰ and at −280‰ and −480‰). The 1:1 line is drawn for reference. The black dots correspond to α = 0.4 and y = 0.3. The precision on the calculated δDIOM values was calculated from ±0.05 random variations on α and y. The precision on the measured δDIOM values is ±100‰, i.e., the width of the step used to construct the histogram reported in Fig. 2.
