Meaning and Definition
A type of igneous rock with a specific, intergrown texture of quartz and feldspar crystals.
In geology, it is a fine-grained granitic rock characterized by a distinctive microscopic intergrowth of quartz and alkali feldspar, typically found as intrusive dikes or the upper parts of larger granitic intrusions. The texture is a key identifier.

FAQ
Frequently Asked Questions
No. Granophyre is a specific type of granite characterized by a distinctive microscopic intergrowth texture of quartz and feldspar. All granophyre is granitic, but not all granite is granophyre.
It is commonly found in shallow intrusive igneous bodies, such as the edges of larger granite plutons, in dikes, or as the fine-grained upper parts of sills and laccoliths.
It comes from the Greek 'phyro', meaning 'mixed' or 'mingled', referring to the intermingled crystal texture.
No. It is a highly specialized technical term. Unless you are studying geology or related earth sciences, you will almost certainly never encounter it.

Granophyre: in British English it is pronounced /ˈɡranə(ʊ)fʌɪə/, and in American English it is pronounced /ˈɡrænəˌfaɪ(ə)r/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think 'grain' + 'fire' -> a rock with a grainy texture formed from fire (magma). 'Phyre' sounds like 'fire'.
Conceptual Metaphor
The rock's texture is often described metaphorically as a 'cuneiform' or 'runic' intergrowth, or likened to ancient writing, due to the interlocking pattern of crystals.
