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.
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.

Skarn vs Diatomite 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 Diatomite 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. Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth. 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 Diatomite information and Skarn vs Diatomite characteristics in the upcoming sections.

Skarn vs Diatomite 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 Diatomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Skarn and Properties of Diatomite. Learn more about Skarn vs Diatomite in the next section. The interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Diatomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Skarn and Diatomite, 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 Diatomite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Source of calcium.

More about Skarn and Diatomite

Here you can know more about Skarn and Diatomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Diatomite consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite and mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Skarn vs Diatomite, 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, Diatomite is available in grey, white, yellow colors. Appearance of Skarn is Dull and that of Diatomite is Soft. Properties of rock is another aspect for Skarn vs Diatomite. The hardness of Skarn is 6.5 and that of Diatomite is 1. The types of Skarn are Endoskarns whereas types of Diatomite 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 Diatomite is white. The specific heat capacity of Skarn is 0.92 kJ/Kg K and that of Diatomite is 0.90 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 Diatomite is heat resistant.
