All eclogites from Syros are very attractive rock assemblages. They are almost exclusively limited in distribution to mafic complexes near the middle of the island.

However, not all the granulite converted to eclogite.

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.

Second, being unusually dense rock, eclogite can play an important role in driving convection within Metamorphic rock names based on parent rock, geologic setting, and metamorphic grade. Metamorphic settings B, R, S B, R, S S B, R, S B, R, S Parent rock Shale Granite Basalt Chert (SiO2) Limestone (CaCO3) GRADE: Low Low - Med Med - High High Very High Slate Phyllite Schist Gneiss Migmatite Gneiss Migmatite Greenstone Blueschist Eclogite Eclogite (above & below; above: 7.4 cm across at its base; below: 9.0 cm across at its widest) from the Münchberg (Muenchberg) Gneiss Massif in Bavaria, Germany. These rocks formed by deep burial metamorphism of near-earliest Ordovician mafic igneous rock during the Devonian Hercynian (Variscan) Orogeny. 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. This changing of rock types is called the "Rock Cycle".
Eclogite Basalt/gabbro S High Red garnets scattered uniformly throughout a finer-grained green groundmass (bright-green pyroxene: omphacite).

Very fresh-looking eclogite with bright green (omphacite) and red (garnet). Nordfjord, Norway. Start studying Parent Rocks Of Metamorphic Rocks. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Its composition depends upon the parent rock material and the temperature/pressure conditions of its metamorphic environment.
Modern-style subduction is characterized by low geothermal gradients and the associated formation of high-pressure low temperature rocks such as eclogite …
Radioactive parent–daughter isotopic variations within rocks are metamorphosed under high-pressure and ultrahigh-pressure conditions to produce eclogites and eclogite facies metamorphic rocks. Eclogite is a metamorphic rock consisting of pyroxene omphacite and pyrope-rich garnet. Eclogite is a rare but geologically significant rock type.

You can also know all the list of rocks in Opaque Rocks, Translucent Rocks and Transparent Rocks. This pyroxene-eclogite is of special interest inasmuch as diamonds have been found as enclosures of the garnet of the rock, and according to one prevailing view eclogite is the parent rock of the diamonds of the South African fields, the diamonds of the "pipes" being derived from the explosive disruption of deep-seated masses of diamantiferous griquaite.
