APPLICATION OF THE ICP‐MS TECHNIQUE TO TRACE ELEMENT ANALYSIS OF PERIDOTITES AND THEIR MINERALS

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.
