In the ultrahigh-pressure metamorphic Kimi Complex garnet-spinel metaperidotites with layers of clinopyroxenites occur. A detailed geochemical investigation using major-trace element relations and major-element modelling indicates that the peridotites represent mantle residues originated after variable melt extraction, along an adiabatic path starting from high- to ultrahigh-pressures. The clinopyroxenites represent HP clinopyroxene-rich cumulates probably formed within the garnet and/or Cr-spinel peridotite stability field.
