5 Formation
5.1 Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Skarn is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Novaculite forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The formation of Novaculite can be either of chemical or biological origin.

Skarn vs Novaculite 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 Skarn and Novaculite Reserves. Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin. Novaculite is a dense, hard, fine-grained, siliceous metamorpic rock which is a type of chert that breaks with conchoidal fracture. 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 Skarn vs Novaculite information and Skarn vs Novaculite characteristics in the upcoming sections.

Skarn vs Novaculite 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. Skarn vs Novaculite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Skarn and Properties of Novaculite. Learn more about Skarn vs Novaculite in the next section. The interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Novaculite include Countertops, Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Skarn and Novaculite, they have various applications in construction industry. The uses of Skarn in construction industry 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, Gold and silver production, Manufacture of magnesium and dolomite refractories and that of Novaculite include Arrowheads, Building houses or walls, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Knives, Landscaping, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone, Spear points, Used to sharpen metal tools and weapons.

More about Skarn and Novaculite

Here you can know more about Skarn and Novaculite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Novaculite consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite and mineral content of Novaculite includes Quartz, Silicon. You can also check out the list of all Metamorphic Rocks. When we have to compare Skarn vs Novaculite, the texture, color and appearance plays an important role in determining the type of rock. Skarn is available in black, brown, colourless, green, grey, white colors whereas, Novaculite is available in black, brown, green, grey, red, white colors. Appearance of Skarn is Dull and that of Novaculite is Glassy or Pearly. Properties of rock is another aspect for Skarn vs Novaculite. The hardness of Skarn is 6.5 and that of Novaculite is 7. The types of Skarn are Endoskarns whereas types of Novaculite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Skarn is light to dark brown while that of Novaculite is colorless. The specific heat capacity of Skarn is 0.92 kJ/Kg K and that of Novaculite is 0.74 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Skarn is heat resistant whereas Novaculite is heat resistant, impact resistant, pressure resistant, wear resistant.
