  1. LREEs total LREEs (La to Gd), HREEs total HREEs (Tb to Lu), (La/Yb)N and (La/Sm)N are normalized concentration ratios in the samples; δCe is the value of the Ce anomaly calculated by δCe = [(CeN)/((LaN*PrN)1/2)], δEu is the value of the Eu anomaly calculated δEu = [(EuN)/((SmN*GdN) 1/2)]; CeN, EuN, LaN, PrN, SmN, and GdN are normalized values against chondrite; R(L/H) = LREEs/HREEs.
