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.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

Skarn vs Oolite 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 Oolite 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. Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite. 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 Oolite information and Skarn vs Oolite characteristics in the upcoming sections.

Skarn vs Oolite 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 Oolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Skarn and Properties of Oolite. Learn more about Skarn vs Oolite in the next section. The interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Skarn and Oolite, 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 Oolite include Cement manufacture, Cobblestones, Landscaping.

More about Skarn and Oolite

Here you can know more about Skarn and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Oolite consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Metamorphic Rocks. When we have to compare Skarn vs Oolite, 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, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Skarn is Dull and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Skarn vs Oolite. The hardness of Skarn is 6.5 and that of Oolite is 3-4. The types of Skarn are Endoskarns whereas types of Oolite 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 Oolite is white. The specific heat capacity of Skarn is 0.92 kJ/Kg K and that of Oolite is Not Available. 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 Oolite is heat resistant, wear resistant.
