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.

The eclogite facies is the facies at the highest pressure and high temperature. It is named for the metabasic rock eclogite. The eclogite facies has the mineral assemblages: In metabasites: omphacite + garnet ± kyanite, quartz, hornblende, zoisite; In metagranodiorite: quartz + phengite + jadeite/omphacite + garnet; In metapelites: Eclogite is an unusually dense metamorphic rock, typically of basaltic composition, that represents a recorder and/or driving force for planetary-scale processes and evolution. 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.” www.CaledonianRockShop.com #mineralcollecting #mineralspecimen #mineralcollection #rockhounding #rockhound #minerals #mineral #rocks #rock #fineminerals #min Eclogite is a metamorphic rock found in gneisses, in sizes from small fist-sized pockets just a few centimetres in diameter to large belts that several hundred metres. “The rock was first described in Norway about 100 years ago, and since then scientists from all over the world have flocked to Norway’s West Coast to learn more about eclogite,” says Engvik.

This work integrates whole-rock geochemistry with the mineral chemistry of of LT eclogite, garnet blueschist and epidote ± garnet amphibolite facies rocks

A metamorp Metamorphic rock is formed underground through a process that changes a rock's molec The two characteristics used to classify metamorphic rocks are foliation and lineation. These rocks are identified by the presence of certain mineral types The two characteristics used to classify metamorphic rocks are foliation and lineati As lithospheric plates are subducted, rocks are metamorphosed under high- pressure and ultrahigh-pressure conditions to produce eclogites and eclogite facies Eclogite. Eclogite is a dense, green plutonic rock composed of coarse grains of green, sodium-rich pyroxene (omphacite) and pale pink, magnesium rich garnet The pale green pyroxene and red garnet are diagnostic of this rock.

Garnet in eclogites begins to grow well before the peak of metamorphism and traps other minerals within it as inclusions. These inclusions provide samples of the rock before it fully recrystallized as an eclogite, and quantitative thermobarometry of them allows us to track the pressure and temperature environments of the ancient subduction zone that formed these beautiful, enigmatic rocks.

An unusually dense rock, eclogite can play an important role in driving convection within the solid Earth. 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. 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. They are formed when volcanic Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature.

Samples of felsic gneisses, garnet amphibolites and one retrogressed eclogite were studied. Quartz, plagioclase, microcline, biotite and hornblende were the main minerals present in the felsic rocks. Eclogite xenoliths are unusual chunks of rock from the Earth's mantle that appear to represent ancient oceanic crust (seafloor) that have been tectonically f The occurrence of eclogite, (a type of metamorphic rock created by high pressure (>1 GPa)), is explained using a model that incorporates subduction. Proterozoic - Wikipedia At a depth of greater than 60 kilometers, the basalt of the oceanic crust is converted to a metamorphic rock called eclogite.

Aulbach et al. Reference Aulbach, Creaser Metamorphic rock that contains amphibole, especially the species hornblende and actinolite, as well as plagioclase. Grouping of rocks composed mainly of amphibole and plagioclase feldspar, with little or no quartz. Eclogite (above & below; above: 7.4 cm across at its base; below: 9.0 cm across at its widest) from the Münchberg (Muenchberg) Gneiss Massif in Bavaria, Germany.

This type of metamorphic rock is the name of highest-grade metamorphic facies. The high pressures necessary for the stabilisation of eclogites in metabasic rocks andgarnetperidotitesinultrabasic rocks havebeen long recognised and experimentally established.
