Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. Eclogite is available in black, brown, colourless, green, grey, pink, white colors. The streak of a rock is the color of powder produced when … The mineral content of Eclogite rock includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite and The compound content of Eclogite rock includes Aluminium Oxide, NaCl, CaO, Carbon Dioxide, Iron(III) Oxide, Magnesium Carbonate, MgO, Sodium Oxide, Potassium, Sodium. 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.
In the present paper the name is applied to a rock derived from some eruptive and bearing garnets in a matrix composed The depth of the granulite to eclogite transition is predicted to be dependent upon whole-rock composition, including ferrous:ferric iron ratio. Natural omphacite-bearing granulite is predicted to form a transitional stage between eclogite and high- P garnet granulite for monzodioritic to gabbroic compositions. Norock & Co`s Eclogite (eklogitt) advantages of using High density material (HD Material) for Ballasting, Scour protection for/in/around offshore constructions, such as windmills (wind farms), pipelines, cables & shore lines, concrete and steel platforms and fundations ets. Weight of Eclogite (density 3,20 kg/dm ) Understanding the electrical conductivity of high pressure metamorphic rocks is essential to constrain the compositions in the subduction zone and continental crust. In this study, we calculated the electrical conductivity for such rocks sampled from the central Qiangtang metamorphic belt in the northern Tibetan Plateau. The results reveal that, when aqueous fluids are absent, the conductivity Eclogite ( pronounced /ˈɛklədʒaɪt/) is a coarse-grained mafic ( basaltic in composition) metamorphic rock.
Rock & Ecology.
Eclogite forms at pressures greater than those typical of the crust of the Earth. An unusually dense rock, eclogite can play an important role in driving convection within the solid Earth. The fresh rock can be striking in appearance, with red to pink garnet (almandine-pyrope) in a green matrix of sodium-rich pyroxene (omphacite).
The original eclogite was dominated by the garnet & omphacite. After uplift from mantle depths, the eclogite underwent retrograde metamorphism.
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.
Durable. Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges 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 continental crust. In some retrogressed eclogites and accompanying more silica-rich rocks, UHP (ultrahigh-pressure) metamorphism has been recognized only because of the preservation of coesite and/or diamond inclusions within trace minerals such as Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. 1.2 History. 1.2.1 Origin.

Eclogite in hand sample. Sheared eclogite from the Italian Alps. 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.
For instance, rocks are used in construction, for manufacturing substances and making medicine and for the production of gas. Rocks are also extremely v
