Eclogite
A high P/T metamorphic rock composed of more than 75% vol. garnet (often pyrope or Mg-rich almandine ) and omphacite (Na-Ca-Al-Mg clinopyroxene ). Both must be present and neither component more than 75% vol. Eclogite never contains plagioclase. Rutile, kyanite, and quartz are typically present.
May be confused with garnet clinopyroxenite .
