Hornfels may be used during construction projects or in the building of roadways. They may also be used as whetstones.

Hornfels
Hornfels or gneiss are possible metamorphic rock with a greywacke protolith.
Hornfels is a type of rock that is metamorphic. They usually have bands and fine grain, and can come in different colors, such as light gray and dark gray.

Hornfels is a metamorphic rock formed by the contact between mudstone / shale, or other clay-rich rock, and a hot igneous body, and represents a heat-altered equivalent of the original rock. This process is termed contact metamorphism. Because pressure is not a factor in the formation of hornfels, it lacks the foliation seen in many metamorphic rocks formed under high pressure and temperature regimes. Pre-existing bedding and structure of the parent rock is generally destroyed during the formation of hornfels.
