Etymology
From an old Swedish mining term originally used to describe a type of silicate gangue or waste rock.
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

Skarn vs Turbidite 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 Turbidite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Skarn and Properties of Turbidite. Learn more about Skarn vs Turbidite in the next section. The interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Skarn and Turbidite, 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 Turbidite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement.
More about Skarn and Turbidite
Here you can know more about Skarn and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Turbidite consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Skarn vs Turbidite, 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, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Skarn is Dull and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Skarn vs Turbidite. The hardness of Skarn is 6.5 and that of Turbidite is 3. The types of Skarn are Endoskarns whereas types of Turbidite 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 Turbidite is white, greenish white or grey. The specific heat capacity of Skarn is 0.92 kJ/Kg K and that of Turbidite 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.Skarn is heat resistant whereas Turbidite is heat resistant.
