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.

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. These rocks formed by deep burial metamorphism of near-earliest Ordovician mafic igneous rock during the Devonian Hercynian (Variscan) Orogeny. 2011-07-02 · A high-pressure, high-temperature, coarse-grained metamorphic rock consisting primarily of pink-red garnet (almadine-pyrope variety) and green pyroxene (omphacite, a sodium-rich variety).

Discovery and brief history of eclogites Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

in the eclogite minerals during their formation were probably expelled from the zone of an epidote-biotite-plagioclase rock surmunding eclogite bodies. Che.

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 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 term "eclogite" was first introduced into the geological literature of Europe in 1822 by Haiiy in his Traith de mineralogie, in which he gave the name to a rock composed chiefly of green augite and garnets. In the present paper the name is applied to a rock derived from some eruptive and bearing garnets in a matrix composed

The rock is dominated by four minerals: pyrope garnet (reddish brown rounded crystals), omphacite pyroxene (greenish), glaucophane (bluish), and muscovite mica (whitish patches).

Eclogite in thin section. Stay tuned! 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.

Because eclogite is a typical high-pressure rock formed within subduction zones, unraveling the metamorphic evolution of Precambrian eclogites with pre-Neoproterozoic ages is important in order to study the evolution of the early style of subduction occurring prior to the Neoproterozoic. Precambrian eclogites are rare worldwide.

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 or metamorphic rocks rich in such mafic minerals 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. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature.
