Definition

A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

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

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Serpentinite and Hornfels

Here you can know more about Serpentinite and Hornfels. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Hornfels consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Hornfels includes Andalusite. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Hornfels, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Hornfels is available in brown, dark greenish - grey, green, reddish brown colors. Appearance of Serpentinite is Rough and Dull and that of Hornfels is Dull. Properties of rock is another aspect for Serpentinite vs Hornfels. The hardness of Serpentinite is 3-5 and that of Hornfels is 2-3. The types of Serpentinite are Jadeitite 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 Serpentinite is white, greenish white or grey while that of Hornfels is . The specific heat capacity of Serpentinite is 0.95 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.Serpentinite is heat resistant whereas Hornfels is heat resistant, impact resistant, pressure resistant.
