Definition
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
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

Formation
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
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.

More about Marble and Hornfels
Here you can know more about Marble and Hornfels. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marble and Hornfels consists of mineral content and compound content. The mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz and mineral content of Hornfels includes Andalusite. You can also check out the list of all Metamorphic Rocks. When we have to compare Marble vs Hornfels, the texture, color and appearance plays an important role in determining the type of rock. Marble is available in black, blue, brown, grey, pink, white colors whereas, Hornfels is available in brown, dark greenish - grey, green, reddish brown colors. Appearance of Marble is Veined and Shiny and that of Hornfels is Dull. Properties of rock is another aspect for Marble vs Hornfels. The hardness of Marble is 3-4 and that of Hornfels is 2-3. The types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble whereas types of Hornfels are Biotite hornfels. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Marble is white while that of Hornfels is unknown. The specific heat capacity of Marble is 0.88 kJ/Kg K and that of Hornfels is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Marble is heat resistant whereas Hornfels is heat resistant, impact resistant, pressure resistant.
