The formation of these rocks is the result of contact metamorphism of shales and basalts. Streak of Hornfels is unknown while its cleavage is perfect. Higher quality stone is quarried, cut, and polished for architectural use. Hornfels is an unusual and relatively rare stone used in making flaked stone tools, and which is found in Aboriginal archaeological sites in Victoria, Australia.

Hornfels, with its alternating bands of dark and light crystals, is a good example of how minerals rearrange themselves during metamorphism. Marble, granular limestone or dolomite (i.e., rock composed of calcium-magnesium carbonate) that has been recrystallized under the influence of heat, pressure, and aqueous solutions. Crushing shale and heating it with limestone makes cement for the construction industry. Metamorphic rock - Metamorphic rock - Classification of metamorphic rocks: Because of the diverse chemistry, mineralogy, and primary origin of metamorphic rocks and because of the diverse fabrics or textures that may develop depending on the stresses that may operate during their formation, there is no simple, universally used classification of these rocks. What happens next? Extreme pressure may also lead to foliation , the flat layers that form in rocks as the rocks are squeezed by pressure (figure 2).
