Peritectic reactions of orthopyroxene and olivine with melts are efficient in governing the regular fractional evolution of the ultrabasic and basic magmas and correlates well with petrochemical trends for the garnet-bearing peridotite and eclogite rocks. Thus, the role of olivine and orthopyroxene peritectic reactions with formation of garnet and clinopyroxene is crucial as a physico-chemical “bridge” for the fractional magmatic evolution of the material of the upper-mantle garnet-peridotitic facies between the ultrabasic peridotite-pyroxenitic and basic eclogitic compositions
