Definition of eclogite in English: eclogitenoun ˈɛklɒdʒʌɪtˈekləˌjīt mass nounGeology A metamorphic rock containing granular minerals, typically garnet and pyroxene. Example sentencesExamples - This textural variety of titanite is common in the more intensely amphibolitized eclogite, and although the mineral-forming reactions are similar to the framboidal-textured varieties, no rutile cores have been found in these grains.
- 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.
Origin Mid 19th century: from French, from Greek eklogē 'selection' (with reference to the selective content of the rock) + -ite1.
