Eclogite - Wikipedia Eclogite ( ˈɛklədʒaɪt ) is a metamorphic rock containing garnet (almandine - pyrope) hosted in a matrix of sodium -rich pyroxene (omphacite) Accessory minerals include kyanite, rutile, quartz, lawsonite, coesite, amphibole, phengite, paragonite, zoisite, dolomite, corundum and, rarely, diamond
Eclogite : Compositions, Formation, Properties - Geology Science Eclogite is a type of metamorphic rock with distinct mineral composition and texture, typically formed under high-pressure and high-temperature conditions deep within the Earth’s crust The name “eclogite” is derived from the Greek words “eklogē,” meaning selection or choice, and “lithos,” meaning rock
Eclogite | Metamorphic, Mafic Minerals Garnet | Britannica 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 Meanings and Crystal Properties - The Crystal Council 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: Mineral information, data and localities. - mindat. org Eclogites are often classified based on their geological setting and temperature of formation A much used classification system is based on work by Coleman et al (1965) and Carswell (1990) In this system the eclogite facies are subdivided into groups A, B or C:
Eclogites: back to the surface - Metageologist - All-geo Eclogites are beautiful rocks that form deep within subduction zones The vast majority of subducted oceanic crust becomes more dense than the surrounding mantle rocks and travels to the strange world of the deep earth Lucky for us, small volumes make it back to the surface How does this happen?
ECLOGITE Eclogite is an attractive, uncommon, crystalline-textured, very high-grade metamorphic rock It is dominated by green red minerals The red is pyrope or almandine garnet The green is omphacite pyroxene Eclogite appears to be moderately common in portions of the upper mantle, but it occurs in very few places at the Earth's surface They have
Eclogite - SpringerLink Eclogites are rather rare rocks occurring as relatively small intercalations, lenses, boudins, or enclosures within various hosts
Eclogite – Sandatlas 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 - Crystallography Gems Eclogites are formed under extreme pressure They help with the study of plate tectonics because they are only found within the mantle and lowermost part of the thickened crust Some Eclogite is unstable when brought to the surface may change into amphibolite or granulite
