Further details and definitions: 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.
