Comment:
a Eu anomaly is calculated using Eu/Eu* = EuN / (SmN 2 + GdN 2) 1/2; the subscript N denotes normalized to chondrite (Anders and Grevesse, 1989).
b Normalized to chondrite (Anders and Grevesse, 1989), the ratio of LREE (light REE, La–Sm) to HREE (heavy REE, Gd–Lu) (i.e. L/HREE), and often approximated by the ratio of La to Yb (i.e. LaN/YbN).
Values in mg/kg given in ppm.
