Serpentinite vs Hornfels


Definition

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   
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'.

Formation

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.

Hornfels vs Serpentinite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Hornfels and Serpentinite Reserves. 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. 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'.. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Hornfels vs Serpentinite information and Hornfels vs Serpentinite characteristics in the upcoming sections.

Hornfels vs Serpentinite 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 Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hornfels and Properties of Serpentinite. Learn more about Hornfels vs Serpentinite in the next section. The interior uses of Hornfels include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Hornfels and Serpentinite, they have various applications in construction industry. The uses of Hornfels in construction industry include For road aggregate, Roadstone and that of Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.

More about Hornfels and Serpentinite

Here you can know more about Hornfels and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornfels and Serpentinite consists of mineral content and compound content. The mineral content of Hornfels includes Andalusite and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Hornfels vs Serpentinite, 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, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Hornfels is Dull and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Hornfels vs Serpentinite. The hardness of Hornfels is 2-3 and that of Serpentinite is 3-5. The types of Hornfels are Biotite hornfels whereas types of Serpentinite are Jadeitite. 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 Serpentinite is white, greenish white or grey. The specific heat capacity of Hornfels is 0.84 kJ/Kg K and that of Serpentinite is 0.95 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 Serpentinite is heat resistant.
