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
* PSAXX : Potential source Area XXX
* 2SE : Two standard error
* (Eu/Eu*)N : Europium anomaly calculated following : (Eu/Eu*)N = EuN/ racine(SmN + GdN).
* EuN is Europium concentration in the sample normalized to Europium concentration in the Upper Continental Crust.
* SmN is Samarium concentration in the sample normalized to Samarium concentration in the Upper Continental Crust.
* GdN is Gadolinium concentration in the sample normalized to Gadolinium concentration in the Upper Continental Crust.
* Method: HF-HNO3 acid digestion followed by isotope ratio measurements using thermal ionization mass spectrometry (TIMS Triton, ThermoFisher)
* Information : The Bodélé Depression samples (prefix: CH) were analyzed as bulk material.
