Keratophyre is a type of volcanic rock that is characterised by its fine-grained texture and typically reddish or brown colour. It is composed of a mixture of minerals, including feldspar, quartz, and biotite or hornblende.

It is a rare rock type that is found in certain regions around the world, and is commonly associated with the formation of volcanic plugs or dikes.

Keratophyre has many practical applications, including as a construction material, in road-building, and as a source of mineral aggregates.
