Device: Neptune Plus multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS) with an Apex-Q desolvation nebulizer
Lead isotope ratio data are reported as 206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb, 208Pb/206Pb, and 207Pb/206Pb ratios. Uncertainties for each sample measurement is presented as the 95% confidence interval (CI). Presented graphically on a plot which includes representative ranges of the lead isotopic ratios of various materials.
Plot of 207Pb/206Pb versus 208Pb/206Pb for the tested samples.
