Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

Laterite vs Peridotite 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. Laterite vs Peridotite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Laterite and Properties of Peridotite. Learn more about Laterite vs Peridotite in the next section. The interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Peridotite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Laterite and Peridotite, they have various applications in construction industry. The uses of Laterite in construction industry include Cobblestones, For road aggregate, Landscaping, Roadstone and that of Peridotite include As dimension stone, Cobblestones.
More about Laterite and Peridotite
Here you can know more about Laterite and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Peridotite 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 Peridotite 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 Peridotite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Peridotite is available in dark greenish - grey colors. Appearance of Laterite is Rough and Banded and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Laterite vs Peridotite. The hardness of Laterite is 2 and that of Peridotite is 5.5-6. The types of Laterite are Not Available whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite and Peridotite is white. The specific heat capacity of Laterite is Not Available and that of Peridotite is 1.26 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 Peridotite is heat resistant, pressure resistant, wear resistant.
