Formation

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.  
Kenyte is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Skarn vs Kenyte 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 Kenyte 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. Kenyte is a variety of porphyritic phonolite or trachyte rock with rhomb shaped phenocrysts of anorthoclase with variable olivine and augite in a glassy matrix. 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 Kenyte information and Skarn vs Kenyte characteristics in the upcoming sections.

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

More about Skarn and Kenyte

Here you can know more about Skarn and Kenyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Kenyte consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite and mineral content of Kenyte includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Metamorphic Rocks. When we have to compare Skarn vs Kenyte, the texture, color and appearance plays an important role in determining the type of rock. Skarn is available in black, brown, green, grey, white colors whereas, Kenyte is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Skarn is Dull and that of Kenyte is Banded and Foilated. Properties of rock is another aspect for Skarn vs Kenyte. The hardness of Skarn is 6.5 and that of Kenyte is 5.5-6. The types of Skarn are Endoskarns whereas types of Kenyte are Foidolite. 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 Kenyte is white, greenish white or grey. The specific heat capacity of Skarn is 0.92 kJ/Kg K and that of Kenyte 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.Skarn is heat resistant whereas Kenyte is heat resistant, impact resistant, wear resistant.
