Formation

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

Pyrolite 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.

Laterite vs Pyrolite 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 Pyrolite Reserves. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt. 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 Pyrolite information and Laterite vs Pyrolite characteristics in the upcoming sections.

More about Laterite and Pyrolite

Here you can know more about Laterite and Pyrolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Pyrolite 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 Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Pyrolite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Pyrolite is available in dark greenish - grey colors. Appearance of Laterite is Rough and Banded and that of Pyrolite is Rough and Shiny. Properties of rock is another aspect for Laterite vs Pyrolite. The hardness of Laterite is 2 and that of Pyrolite is 5.5-6. The types of Laterite are Laterite whereas types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite and Pyrolite is white. The specific heat capacity of Laterite is 0.92 kJ/Kg K and that of Pyrolite is 1.25 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 Pyrolite is heat resistant, pressure resistant, wear resistant.
