Formation

Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

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.

Laterite 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 Laterite and Skarn Reserves. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. 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 Laterite vs Skarn information and Laterite vs Skarn characteristics in the upcoming sections.

The uses of Laterite in construction industry include Cobblestones, For road aggregate, Landscaping, Roadstone 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.

More about Laterite and Skarn

Here you can know more about Laterite and Skarn. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Skarn consists of mineral content and compound content. The mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene and mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Skarn, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Skarn is available in black, brown, green, grey, white colors. Appearance of Laterite is Rough and Banded and that of Skarn is Dull. Properties of rock is another aspect for Laterite vs Skarn. The hardness of Laterite is 2 and that of Skarn is 6.5. The types of Laterite are Laterite 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 Laterite is white while that of Skarn is light to dark brown. The specific heat capacity of Laterite is 0.92 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.Laterite is heat resistant, pressure resistant whereas Skarn is heat resistant.
