Definition
Hornfels is a metamorphic rock formed by the contact between mudstone or other clay rich rock, and a hot igneous body, and represents a heat altered equivalent of the original rock
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Hornfels is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

Hornfels vs Marble Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Hornfels vs Marble characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hornfels and Properties of Marble. Learn more about Hornfels vs Marble in the next section. The interior uses of Hornfels include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Marble include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Hornfels and Marble, they have various applications in construction industry. The uses of Hornfels in construction industry include For road aggregate, Roadstone and that of Marble include As dimension stone.
More about Hornfels and Marble
Here you can know more about Hornfels and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornfels and Marble consists of mineral content and compound content. The mineral content of Hornfels includes Andalusite and mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Hornfels vs Marble, the texture, color and appearance plays an important role in determining the type of rock. Hornfels is available in brown, dark greenish - grey, green, reddish brown colors whereas, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Hornfels is Dull and that of Marble is Veined and Shiny. Properties of rock is another aspect for Hornfels vs Marble. The hardness of Hornfels is 2-3 and that of Marble is 3-4. The types of Hornfels are Biotite hornfels whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hornfels is unknown while that of Marble is white. The specific heat capacity of Hornfels is 0.84 kJ/Kg K and that of Marble is 0.88 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Hornfels is heat resistant, impact resistant, pressure resistant whereas Marble is heat resistant.
