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.
Sovites are formed due to low degrees of partial melting of rocks.

Hornfels vs Sovite 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 Sovite 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. Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock. 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 Sovite information and Hornfels vs Sovite characteristics in the upcoming sections.

Hornfels vs Sovite 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 Sovite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hornfels and Properties of Sovite. Learn more about Hornfels vs Sovite in the next section. The interior uses of Hornfels include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Sovite include Decorative aggregates and Homes. Due to some exceptional properties of Hornfels and Sovite, they have various applications in construction industry. The uses of Hornfels in construction industry include For road aggregate, Roadstone and that of Sovite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Hornfels and Sovite

Here you can know more about Hornfels and Sovite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornfels and Sovite consists of mineral content and compound content. The mineral content of Hornfels includes Andalusite and mineral content of Sovite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite. You can also check out the list of all Metamorphic Rocks. When we have to compare Hornfels vs Sovite, 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, Sovite is available in black, brown, green, grey, pink, white colors. Appearance of Hornfels is Dull and that of Sovite is Dull, Banded and Foilated. Properties of rock is another aspect for Hornfels vs Sovite. The hardness of Hornfels is 2-3 and that of Sovite is 3. The types of Hornfels are Biotite hornfels whereas types of Sovite are Carbonatite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hornfels is while that of Sovite is white. The specific heat capacity of Hornfels is 0.84 kJ/Kg K and that of Sovite 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.Hornfels is heat resistant, impact resistant, pressure resistant whereas Sovite is heat resistant, pressure resistant.
