AbstractWith the development of analytical techniques, lithium (Li) and oxygen (0) isotope in -situ microanalyses become more important in earth sciences. In this paper, we summarized the chemical compositions of olivine (Mg-# = 89. 6 similar to 94. 2), clinopyroxene (Mg-# = 90. 0 -91. 9) and orthopyroxene (Mg-# = 90. 1 similar to 92. 1) reference materials for both Li and 0 isotope analyses, and report newly obtained trace elements. The major element contents of these three reference materials are homogeneous. There is no significant matrix effect in the three kinds of reference materials on 0 isotopes during SIMS analyses, whereas the matrix effect is a linear function of composition, with delta(7) Li increasing by 1%c for each mole percent decrease in forsterite component for olivine. The contents of Ni, Co, and Zn in olivine are 1 to 1. 5 times as much as the primary mantle, while the contents of large ion lithophile elements and rare earth elements are quite low. The contents of trace elements in clinopyroxene obtained by SN-ICP-MS and LA-ICP-MS are consistent within analytical errors except for a few elements, and thus the clinopyroxene can be the potential reference materials for trace element analysis. They all show enrichment in V, Sc, Cr, and Ga relative to other transition elements in primary mantle -normalized diagrams and significant depletion in large ion lithophile elements Rb and Ba relative to Th and U. The rare earth elements in clinopyroxene are slightly fractionated. The contents of transition elements (Cr, V and Sc) in orthopyroxene are close to that of the primary mantle, whereas the contents of large ion lithophile elements and light rare earth elements are too low to be detected accurately by either LAICP-MS or SN-ICP-MS.
