Abstract

Abstract

Two types of "complex" peridotitic xenoliths exist in the earth mantle and/or lower crust: "polymict" peridotitic xenoliths and "composite" peridotitic xenoliths. Composite peridotitic xenoliths usually comprise two or more components of peridotite and pyroxenite/granulite or of peridotite with pyroxenite veins and can be easily identified in petrography, sometimes in hand samples. But the polymict peridotitic xenoliths are tectonites composed of minerals from various peridotites and/or pyroxenites and melts and brought together by mantle shear zone and difficult to identify in petrography, they must be classified by compositional analyses of constituent minerals. Polymict peridotitic xenoliths have only been found in kim-berlite pipes from the Kaapvaal craton, South Africa so far. These polymict peridotitic xenoliths originated from the mantle shear zone and recorded the whole evolutionary processes of fluid/melt-assisted mantle deformation and metasomatism. Composite peridotitic xenoliths are relatively common and occur in global basalts and kimberlites of all kinds. Composite peridol-itic xenoliths have a variety of origins such as mantle deformation, crust-mantle transitional zone sampling, metasomatism and accumulates, etc.. These composite peridotitic xenoliths also record the intermediate stage of metasomatism and modification processes of the lithospheric mantle and/or lower crust. Therefore, these rare and important complex peridotitic xenoliths provide the most direct samples for the geodynamic evolution of the continental lithosphere.
