Gneiss vs Skarn

Gneiss vs Skarn 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 Gneiss and Skarn Reserves. Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin. 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 Gneiss vs Skarn information and Gneiss vs Skarn characteristics in the upcoming sections.

Gneiss vs Skarn 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. Gneiss vs Skarn characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Gneiss and Properties of Skarn. Learn more about Gneiss vs Skarn in the next section. The interior uses of Gneiss include Countertops, Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Gneiss and Skarn, they have various applications in construction industry. The uses of Gneiss in construction industry include As dimension stone and that of Skarn 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.

Gneiss is available in black, brown, pink, red, white colors whereas, Skarn is available in black, brown, green, grey, white colors. Appearance of Gneiss is Foliated and that of Skarn is Dull. Properties of rock is another aspect for Gneiss vs Skarn. The hardness of Gneiss is 7 and that of Skarn is 6.5. The types of Gneiss are Augen Gneiss, Henderson Gneiss, Lewisian Gneiss, Archean and Proterozoic Gneiss. whereas types of Skarn are Endoskarns. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Gneiss is white while that of Skarn is light to dark brown. The specific heat capacity of Gneiss is 0.70 kJ/Kg K and that of Skarn is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Gneiss is heat resistant, pressure resistant, scratch resistant, wear resistant whereas Skarn is heat resistant.
