Major minerals of eclogite include garnet, omphacite, phengite, rutile and amphibole, and their sorrounding rocks are garnet phengite schist and blueschist. Garnet phengite schist is mainly composed by garnet, phengite and quartz, and blueschist is mainly composed by garnet, amphibolite and phengite. Petrology and mineralogy data suggest that the eclogite has experienced three stages of metamorphism. The evolution of eclogite is an evidence of the subduction of Paleo-Tethys and copt; mso-font-kerning: 0pt" lang=EN-US>llision between Gondwana and Laurasia in the Northern Tibetan plateau.&nbsp;p>p>
