Eclogite is rock of mafic composition (igneous rock relatively low in silica) that has been buried to 50 kilometres or more. At this depth, everyday minerals such as plagioclase feldspar or augite are no longer stable and they break down, allowing the rock to grow new denser (more attractive) minerals that are better suited to higher pressures. Eclogitizationis the tectonicprocess in which the high-pressure, 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 (Muenchberg Gneiss Massif; Early Ordovician protolith, about 480 Ma; Late Devonian metamorphism, about 365 Ma; Wissenstein, just south of Stammbach, Frankenwald Forest, Bavaria, southeast-central Germany) 1 (15097930745).jpg 734 × 837; 855 KB Mantle eclogites represent a minor component (<5 %) of the lithospheric mantle beneath cratons that is dominated by peridotitic material (e.g.

The high-P mineral Abstract. 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 Subduction-related eclogites are products of their igneous, metamorphic, fluid- rock, and tectonic histories.

Eclogite is an unusually dense metamorphic rock, typically of basaltic composition, that represents a recorder and/or driving force for planetary-scale processes and evolution.

Eclogite is an unusually dense metamorphic rock, typically of basaltic composition, that represents a recorder and/or driving force for planetary-scale processes and evolution. Eclogite-facies metamorphic conditions encompass a wide range of pressure–temperature space from deep crustal to mantle depths, reflecting tectonic setting. 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 Eclogite Eclogite: 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).

[ ĕk ′lə-jīt′ ] A greenish, coarse-grained metamorphic rock consisting of pyroxene, quartz, and feldspar with large red garnet inclusions. Eclogites form under conditions of high pressure and moderate to high temperatures.
