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 from Visnes has a high average density above 3,2 t/m3. This, together with high compressive strength (> 150MPa), provides excellent features for ballasting, overlay and protection of submerged installations. The relatively high submerged weight gives the eclogite its advantage in achieving stability underwater.

Eclogite parageneses comprise garnet, omphacite, amphibole, phengite, clinozoisite, quartz, dolomite and rutile. Accessory minerals include pyrite, apatite, allanite and zircon. Titanium is mainly present as rutile, mostly as grains occupying the matrix. A lesser occurrence is as numerous but tiny inclusions within silicates.
About Eclogite Hide A high P/T metamorphic rock composed of more than 75% vol. garnet (often pyrope or Mgrich almandine) and omphacite (NaCaAlMg clinopyroxene ). Both must be present and neither component more than 75% vol. Eclogite never contains plagioclase. Rutile, kyanite, and quartz are typically present. Classification of Eclogite Hide
Eclogite Meanings, Zodiacs, Planets, Elements, Colors, Chakras, and more. Science Origin of EclogiteEclogite 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 ...
The eclogite velocities obtained in this study are similar to those measured in bimineralic eclogite with the pulsetransmission technique. Kern et al. ( 1999 ) measured mean V P = km s 1, AV P ∼ 2 per cent, Vs = km s 1 and δ V S = km s 1 at 600 MPa in two bimineralic eclogites from the Dabie UHP belt ...
Jun 11, 2021Some blueschist mineralogy that may be present in an eclogite, like glaucophane, may not always be retrograde, but can also occur as relict prograde phases incompletely lost (plus, there are rare eclogite facies blue amphiboles too, like nybøite); greenschist facies minerals like chlorite and actinolite would likely be retrograde, but others ...
Eclogitization is the tectonic process in which the highpressure, metamorphic facies, eclogite (a very dense rock), is formed. This leads to an increase in the density of regions of Earth''s crust, which leads to changes in plate motion at convergent boundaries (where rock sinks beneath other rock).

Eclogite. Eclogite is a nonfoliated, predominantly bimineralic metamorphic rock consisting of garnet and pyroxene. It is easily identifiable by its relatively large, red garnet crystals set in a matrix of finegrained, lightgreen pyroxene. It may also have smaller amounts of accessory minerals like kyanite, rutile, and quartz.
Jan 29, 2022The eclogite pods mainly consist of garnet + omphacite ± lawsonite + phengite + rutile ± glaucophane ± chlorite ± quartz ± epidote (Çetinkaplan et al. 2008; Davis and Whitney 2006, 2008 ). The surrounding blueschists mainly consist of sodic amphibole + garnet + phengite + lawsonite ± epidote ± sodic pyroxene ± quartz (Davis and Whitney 2006 ).
The deep origin of the eclogite xenolith is consistent with reports indicating the possible subduction of continental materials to depths greater than 200 km in the region, which is based on mineral exsolutions in garnet within eclogites from Yangkou in the Chinese Sulu ultrighpressure metamorphic belt ().What is new in our eclogite xenoliths is the discovery of majoritic garnet inclusions ...
The eclogite records peak metamorphic pressures of GPa at 650670 °C, indicating a cold thermal gradient, 250 (±15) °C GPa −1. Our data, combined with old lowtemperature events in the...

Eclogite is an unusually dense metamorphic rock, typically of basaltic composition, that represents a recorder and/or driving force for planetaryscale processes and evolution. Eclogitefacies metamorphic conditions encompass a wide range of pressuretemperature space from deep crustal to mantle depths, reflecting tectonic setting.
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. Cold eclogite may sink as far as the gammaspinel phase change near 500 km depth.
We document an Archean orogenic eclogite, providing robust evidence that subduction of oceanic crust reached to at least 65 to 70 km in depth at circa Ga. This extends the known age of subductionrelated eclogitefacies metamorphism back 400 My, showing that modernstyle plate tectonics operated by the close of the Archean.
The best way to fully understand the advantages of eclogite is to compare it with another typical rock Applications and Advantages There are a number of occasions (ballast, scour protection etc), when using HD material will result in both time and cost saving for your company.

Eclogites: back to the surface 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?
