Definition of eclogite in English:

eclogite

noun ˈɛklɒdʒʌɪtˈekləˌjīt
mass nounGeology
  • A metamorphic rock containing granular minerals, typically garnet and pyroxene.

    Example sentencesExamples

    • A large sample of eclogite was collected from a small bay close to Letterfearn.
    • Specific rock names that record both the parent rock and its mineralogy are relatively rare, but include eclogite, blueschist, and amphibolite.
    • The granulite to eclogite transformation may not occur if water is absent; for example, if ocean crust has been dehydrated as happens when a slab subducts.
    • In similar contrast to the Okenyenya xenolith suite, lithologies such as wehrlite, eclogite and pyroxenite are also absent.
