Trace element data on mantle peridotites were usually obtained with large uncertainty by neutron activation analysis in China previously. We have determined trace element concentration of 173 grains of clinopyroxene (cpx) in 50 peridotite xenoliths from different areas in China using the pro- 关 键 词：TRACE ELEMENT CLINOPYROXENE mantle.
