Eclogite ( pronounced /ˈɛklədʒaɪt/) is a coarse-grained mafic ( basaltic in composition) metamorphic rock. Eclogite is of special interest for at least two reasons. First, it forms at pressures greater than those typical of the crust of the Earth. Second, being unusually dense rock, eclogite can play an important role in driving convection within

This page is about Eclogite Rock,contains Mindat Mineralogy Messageboard, Eclogite may be more fine-grained and darker in appearance ,Metamorphic Rock  18 Nov 2013 In a process called metamorphism ("change in form"), old rocks are turns into greenschist, but under high pressures, it turns into eclogite. The five rocks are blueschist, greenschist, amphibolite, granulite, and eclogite. Index minerals are helpful in determining isograds and metamorphic zones. Mylonite is a metamorphic rock formed by ductile deformation during intense This process involves nearly complete pulverisation of the parent rock so the  Parent rocks can be from any of the three rock types: sedimentary, igneous, eclogite at about 35 km depth, and then eventually sinks deep into the mantle,  Metamorphic facies.

The parent rock can be either sedimentary, igneous, or even another metamorphic rock. The word "metamorphic" comes from Greek and means "To Change Form". The diagram above shows you how the rocks on Earth have been changed continually over time from one rock type to another.

Q3) The eclogite comes from the transformation of basaltic rocks during subduction. What are the two most important factors in the transformation of the rock ? Q4) At the retrogression phase, static transformations can occur on eclogite . The blocks you observe underwent these readily observable changes around here garnets. What is it ?

Thisisfrance  Eclogite (/ ˈɛklədʒaɪt /) is a metamorphic rock formed when mafic igneous rock is subjected to high pressure. 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.

Eclogite is characterized by a pale green pyroxene and a red garnet, making it a striking rock. Since eclogite forms so deep, outcrops are not common. Large crystal in an ultramafic rock peridotite. Hullvann, Norway. Width of sample 18 cm. Lots of garnet crystals (compositionally between almandine and pyrope end-members) in a metamorphic rock eclogite.

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.

Exhumed high pressure terranes are typically > 85% - 90% sialic material with only minor amounts of mafic and ultramafic rock. Most known metabasitic eclogites are blocks in mélange rather than large coherent bodies. The Central Metamorphic terrane (CMt) is a large (~300 km3) coherent, fault The rock name eclogite was coined by Haüy, a founder of crystallography, in 1822. Since the original definition of the name was vague, its meaning was gradually settled through its usage in later years. To constrain the timing from the accretion to the subduction-related metamorphism of the protolith in the Sanbagawa eclogites, we performed zircon U–Pb datings and REE composition analyses on pelitic schist of the Seba eclogite-facies region in the Besshi area in central Shikoku, Japan.

Rutile, kyanite, and quartz are typically present. Haüy coined the term eclogite, meaning “chosen rock”, in 1822, but de Saussure had already observed rocks of this type in the Alps four decades earlier. In these ‘wet’ eclogite rocks it remains stable. ZS Unit Aosta valley, glaucophane bearing eclogite (scanned thin section 50x30mm) showing that glaucophane may be stable under eclogite facies, together with omphcite + grt + rutile.
