(a, b) Garnet porphyroblasts with inclusions of omphacite (Omp), phengite (Ph) and kyanite (Ky), symplectitic texture of diopside (Di) + plagioclase (Pl), and amphibole (Amp) in the matrix. (c) Garnet partly replaced by orthopyroxene (Opx) and plagioclase. Eclogite ("ECK-lo-jite") is an extreme metamorphic rock formed by regional metamorphism of basalt under very high pressures and temperatures. This type of metamorphic rock is the name of highest-grade metamorphic facies. The Shuanghe coesite eclogite has experienced a prolonged metamorphic evolution based on the modifications of texture and mineral assemblage described above. It may be divided into three stages: peak UHP metamorphism (stage A), early retrogression to quartz eclogite (stage B) and late retrogression to condition of the plagioclase stability Une éclogite (terme défini par l'abbé Haüy en 1822 à partir du mot grec grec eklogê, choix, en référence à la sélection de minéraux qui constituent cette roche) [1] est une roche métamorphique qui s'est formée dans le faciès éclogitique, c'est-à-dire ayant subi les conditions de pression et température de ce champ. It is a major mineral component of eclogite along with pyrope garnet and also occurs in blueschist facies and UHP (ultrahigh-pressure) metamorphic rocks.

To understand the relationships between eclogite‐facies mineral assemblages, deformation microstructures, and the seismic properties of subducting oceanic crust, eclogites from the Yuka terrane, North Qaidam ultrahigh‐pressure metamorphic belt, NW China, were studied. The Allalin gabbro is a 2 km05 km block of layered olivinegabbro and troctolite included in the Zermatt^Saas ophiolite nappe of theWestern Alps. Comprehensive texture, mineral and rock composition data together with a thermodynamic analysis of the Traductions en contexte de "eclogite" en anglais-français avec Reverso Context : These rocks preserve igneous textures overprinted by eclogite mineralogy and by textures related to subsequent unloading.

Eclogite is a rare and important rock because it is formed only by conditions typically found in the mantle or the lowermost part of thickened crust..

After uplift from mantle depths, the eclogite underwent retrograde metamorphism. Some of the omphacite pyroxene was altered into glaucophane & muscovite. But the original eclogite’s mineralogy & overall texture is fairly well preserved. Eclogite texture (BSE) and compositional profile across a garnet grain in sample BEL‐1.
