Eclogite - Wikipedia
Eclogite ( / ˈɛklədʒaɪt /) is a metamorphic rock containing garnet (almandine - pyrope) hosted in a matrix of sodium -rich pyroxene (omphacite). Accessory minerals include kyanite, rutile, quartz, lawsonite, coesite, amphibole, phengite, paragonite, …
Eclogite Meanings and Crystal Properties - The Crystal Council
Eclogite is a mafic (high iron & magnesium silicate) metamorphic rock consisting of pink or red Garnet (Pyrope or Almandine) and Omphacite. Omphacite is a sodium rich mineral and member of the Pyroxene crystal family. It’s color can be just about any shade of green and is the matrix for which the Garnets formed.
Eclogite | Metamorphic, Mafic Minerals & Garnet | Britannica
Eclogite, any member of a small group of igneous and metamorphic rocks whose composition is similar to that of basalt. Eclogites consist primarily of green pyroxene (omphacite) and red garnet (pyrope), with small amounts of various other stable minerals—e.g., rutile. They are …
Eclogite - an overview | ScienceDirect Topics
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.

2024年2月8日 · Eclogite is a metamorphic rock. Hence it is a rock that underwent changes in mineral content, mineral composition and structure compared with its precursor, or protolith.
Eclogite: Diamond-Encrusted Ancient Seafloor
2022年5月13日 · Eclogitic diamonds constitute a significant portion of the gem diamond market, and their features embody the dynamic processes unique to Earth. WHAT IS ECLOGITE? Typically, eclogite refers to a colorful red and green metamorphic rock that is made up of two key minerals: grossular-almandine-pyrope garnet and omphacitic clinopyroxene (figure 2 ...
Eclogitization - Wikipedia
Eclogitization is the tectonic process 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 …
Nature and origin of eclogite xenoliths from kimberlites
2004年9月1日 · Eclogite is the original host rock from which diamond was first recovered (Bonney, 1899) and diamond with eclogitic affinity dominates the diamond population at some localities, for example at Orapa (Botswana; Gurney et al., 1991).
Typically, eclogite refers to a colorful red and green meta-morphic rock that is made up of two key minerals: grossu-lar-almandine-pyrope garnet and omphacitic clinopyroxene (figure 2) (Winter, 2010). Additional minerals sometimes present include rutile, coesite, kyanite, and …
Eclogite - chemeurope.com
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.
