Definition of granulite in English:
granulite
noun ˈɡranjʊlʌɪtˈɡrænjəˌlaɪt
mass nounGeology A fine-grained granular metamorphic rock in which the main component minerals are typically feldspars and quartz.
as modifier the granulite facies
Example sentencesExamples
- Two types of terrain are especially characteristic of Archaean geology: greenstone - granite terrains and granulite - gneiss terrains.
- This granulite consists of garnet, biotite, muscovite, quartz, plagioclase and cordierite.
- These rocks display clear prograde metamorphism that peaks in granulite facies.
- 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.
- This indicates that the sapphirine granulite could be a different variety of pelitic granulites.

Geology Resting on top of the granulitic rocks of the Dalsfjord Suite are the arkosic metasediments of the Hoyvik Group which are interpreted as detritus from the Dalsfjord Suite rocks.
Example sentencesExamples
- The researchers studied metamorphic conditions of granulitic rocks in the Zoblitz complex and estimated maximum pressure conditions of 21 kbar at 830°C.
- The Sudete Mountains, NE Bohemian Massif (Czech Republic and Poland), preserve abundant eclogitic and granulitic centimetre - to decimetre-scale boudins enveloped in a predominantly migmatitic matrix.
- Granitic intrusions common in the upper crust are typically products of fluid-absent melting of fertile crustal rocks, leaving granulitic residues and migmatitc complexes.
- Also, those workers noted that eclogites, in particular with felsic composition, are theologically weak, relative to their granulitic equivalents.
Origin
Mid 19th century: from granule + -ite1.
