Meaning and Definition
A granular, high-grade metamorphic rock formed under high temperature and pressure conditions, typically composed of feldspar and quartz.
In geology, a coarse-grained rock that has undergone intense metamorphism, often found in the deep crust and associated with ancient continental roots. In broader scientific contexts, it can refer to the granulite facies, a set of mineral assemblages indicating specific pressure-temperature conditions.

FAQ
Frequently Asked Questions
No. Granite is an igneous rock that forms from the cooling of magma. Granulite is a metamorphic rock formed by the intense heating and compression of pre-existing rocks deep in the crust.
They are typically found in ancient, stable continental cores (cratons), in deeply eroded mountain belts, and as xenoliths (foreign rock fragments) in volcanoes.
It refers to the set of high-temperature and moderate-to-high pressure mineral assemblages that define the metamorphic conditions under which granulite forms.
Yes, unless they are reading highly specialized geological literature. It is not a word needed for general English proficiency.
