Eclogite is a metamorphic rock consisting of pyroxene omphacite and pyrope-rich garnet. Eclogite is a rare but geologically significant rock type. It is common in the upper mantle, especially in regions occupied by subducted oceanic plates. Eclogite is unusually dense for a silicate rock (3.4-3.5 g/cm 3) which suggests that very high pressure was involved in the formation of this rock type.
