OREAS 146 is a rare earth element (REE) certified reference material prepared from mineralised REE + Y material hosted within mafic amphibolites (hornblende-biotite schist). Fifteen laboratories participated in the analytical program to characterise Ce, Dy, Er, Eu, Gd, Ho, La, Lu, Nd, Pr, Sm, Tb, Tm, Yb, Y, U and Th by fusion ICP-MS.
