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.

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. 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 a mafic (high iron & magnesium silicate) metamorphic rock consisting of pink or red Garnet (Pyrope or Almandine) and Omphacite. Omphacite is a sodium rich mineral and member of the Pyroxene crystal family. It’s color can be just about any shade of green and is the matrix for which the Garnets formed.

Eclogite

Eclogite 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.

Metamorphic zircon domains in eclogite and quartz vein show relatively flat patterns of heavy REE without notable Eu anomalies but different cathodoluminescence responses and middle REE (MREE) contents. This indicates their growth in different stages of eclogite facies metamorphism, which are categorized into two groups.

Rutile, kyanite, and quartz are typically present. Discovery and brief history of eclogites 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.”. Later the name was applied to all granular rocks consisting essentially of greenish clinopyroxene and reddish garnet, with a possible Although eclogite is usually considered to be a dense rock, Figure 1 shows that it can have similar densities to various peridotite minerals and assemblages that are believed to make up the mantle between 100 and 400 km.

From Cambridge English Corpus The eclogite is best preserved in the interiors of thick sheets and/or pods. From Cambridge English Corpus Eclogites are rather rare rocks occurring as relatively small intercalations, lenses, boudins, or enclosures within various hosts.
