Eclogite, any member of a small group of igneous and metamorphic rocks whose composition is similar to that of basalt. Eclogites consist primarily of green pyroxene (omphacite) and red garnet (pyrope), with small amounts of various other stable minerals—e.g., rutile.
Eclogite definition is - a metamorphic rock consisting of soda-rich pyroxene and magnesia-rich garnet as essential minerals.
From Cambridge English Corpus Eclogites are rather rare rocks occurring as relatively small intercalations, lenses, boudins, or enclosures within various hosts. About Eclogite Hide 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. Eclogite is a rock that typically forms from high pressure metamorphism of mafic igneous rock at temperatures in excess of 500oC and pressures in excess of 12kbar.
Cold eclogite may sink as far as the gamma-spinel phase change near 500 km depth. Eclogite Mark & Bygg AB - Org.nummer: 5590514146.

Eclogite is a metamorphic rock consisting of pyroxene omphacite and pyrope-rich garnet. It is a rare but geologically significant rock type. It is common in the upper mantle, especially in regions occupied by subducted oceanic plates.
(2007) Metamorphic Rocks - A Classification and Glossary of Terms. Cambridge University Press. The algorithm suggests that the V. Grib eclogite zircon grains have metamorphic origins in that they have Th/U values >0.1, contain only weak zoning visible during CL imaging and have REE N patterns that do not match those of typical magmatic zircons that formed in different environments (for REE N patterns in typical magmatic zircons, see Belousova et al. Reference Belousova, Griffin, O’Reilly and Fisher 2002; Hoskin & Schaltegger, Reference Hoskin and Schaltegger 2003). 2017-09-01 · The rheology of eclogite, garnetite and clinopyroxenite in the peridotitic upper mantle was experimentally investigated in a large volume press combined with in situ synchrotron X-ray diffraction techniques to study the impact on mantle convection resulting from the subduction of oceanic lithosphere.
Streak of Eclogite is white while its cleavage is perfect. Luster of Eclogite is subvitreous to dull and its fracture is not available.

Abstract. The mafic eclogites of the Lanterman Range are the first record of a well -preserved high-pressure assemblage from the Pacific end of the Transantarcti.
Eclogite-facies metamorphic conditions encompass a wide range of pressure–temperature space from deep crustal to mantle depths, reflecting tectonic setting. The rock name eclogite was first used by R. J. Haüy in 1822 for a “fancy rock” composed mainly of two minerals “diallage and garnet accompanied accidentally by kyanite, quartz, epidote, and lamellar amphibole.”.

Eclogite ( pronounced /ˈɛklədʒaɪt/) is a coarse-grained mafic ( basaltic in composition) metamorphic rock. Eclogite is of special interest for at least two reasons. First, it forms at pressures greater than those typical of the crust of the Earth. Second, being unusually dense rock, eclogite can play an important role in driving convection within
