Fig. 3: Isotope ratios of 87Sr/86Sr and 208Pb/204Pb.
Errors on the measurements are smaller than the symbols. Small squares represent the bulk analyses published in Rousseau et al.25 while large symbols correspond to our latest measurements. The geographical groups are identical to those identified in Rousseau et al.25. The Nussloch samples are shown separately from Western Europe as they correspond to both LGM and previous and later samples.
