Abstract
Xenoliths from the Mir pipe and from Shandong and Liaoning provinces were studied according to electron microbeam analysis and ICP-MS. Their mineralogical, geochemical and genetic features are revealed. Minerals of diamondiferous paragenesis were established in xenoliths of the Mir pipe, but not in xenoliths of China. All xenoliths have secondary changes. They are stronger in the xenoliths of China. The distribution of REE shows the involvement of subduction processes in the formation of xenoliths from the Mir pipe. They are not found in xenoliths from China; the influence of metasomatism is clearly manifested in them. РТparameters were calculated: Т=600700 °С, Р=22,5 GPa. They do not correspond to mantle settings and reflect the conditions of metasomatic processes.
