hornfels is a rock or mineral
Hornfels is formed when mudstone or shale come in contact with a hot igneous body and metamorphic rock. This process is called contact metamorphism.
Sandstone
. I would expect to find nonfoliated rock next to a lava flow because the rock can form when rock is subjected to high temperatures. Hornfels, which often forms when magma or lava touches other rock, is nonfoliated.

hornfels is a rock or mineral
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 may be used during construction projects or in the building of roadways. They may also be used as whetstones.
it is found in Mexico
it a bumpy smooth metamophic rock
Hornfels or gneiss are possible metamorphic rock with a greywacke protolith.
sandstone, shale,slate, limestone and diabase
Slate, hornfels, schist, gneiss.
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.
