| Abstract: | Inductively coupled plasma mass spectrometry (ICP-MS) has been applied to the determination of Rb, Sr, Ba, Zr, Hf, Nb, Ta, Th, U, Pb, Sc and 14 REE in peridotites and their constituent minerals: garnet, clinopyroxene, orthopyroxene and olivine. Determination limits for most elements are 1–10 ppb (in the solid sample), with accuracy and precision comparable to those of thermal ionisation and spark-source mass spectrometry. New data on international standards PCC-1, DTS-1, UB-N and JP-1 are reported. |
