Radiogenic isotope signatures (Sr-Nd-Pb) on four different soils and four collected aerosols along the Harmattan corridor


Further details and definitions: εNd : epsilon Nd following the equation : εNd = ((143Nd/144Nd)sample/(143Nd/144Nd)CHUR - 1) * 10,000 . The unit should be "per ten thousand" but it is always expressed without. CHUR : Chondritic Uniform Reservoir with (143Nd/144Nd) = 0.512638 2SE : Two standard error R-SC : Hydrobromic leaching residue of the silt-clay fraction (<20 µm) L-SC : Hydrobromic leaching leachate of the silt-clay fraction (<20 µm) SC : silt-clay (<20 µm) R-Sample Name : Hydrobromic leaching residue of the collected aerosol Bulk-Sample Name : Bulk sample previously analyzed and published in Abouchami et al., (2013) Method: Hydrobromic acid (HBr 0.5 mol/L) selective extraction to remove anthropogenic Pb, followed by HF-HNO3 acid digestion of leachates and residues and isotope ratio measurements using thermal ionization mass spectrometry (TIMS Triton, ThermoFisher).* Information about the table : Note that L-SC and R-SC refer to 0.5 N HBr leachates and residues. SC values are coming from Table S1 (doi:10.1594/PANGAEA.949883). Bulk data coming from Abouchami et al. (2013).
