Introduction.
30
This dataset contains isotopic data, environmental parameters estimated over Europe and
31
location of the investigated sites described in the manuscript. The locations of the studied
32
samples are plotted on the geological map of Europe on figure S1. Trace elements and isotope
33
ratios are presented in Table S1 and Figures S2 and S3. Climate parameters reconstructions
34
for the European region are provided in Figure S4 and.

fs02.pdf (Figure S2): Trace element data normalized to the average concentrations of the
43
upper continental crust[Rudnick and Gao, 2003]. a-d Trace element analyses of the
44
regional sets. (a) Samples from Western Europe, (b) Nussloch samples, (c) Samples from
45
Eastern Germany, (d) Samples from Eastern Europe. Most sediments show similar
46
patterns but clear differences exist concerning the size of the positive Hf and Zr
47
anomalies (grey underlain zone). The proportion of excess zircon varies greatly from site
48
to site. Two samples from Renancourt in Western Europe show differing concentrations
49
that are related to the differing mineralogy of the two grain-size fractions (35 to 50 m

and >50 m) used. Data from the Nussloch samples indicate that the dust source
51
remained unchanged between 34 ka and 18 ka.

Also plotted are linear regression lines for individual sample groups. For (a) and (b) the
56
regression lines can be used to estimate the age of mineral formation (t) which is also
57
plotted.
