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

Peridotite vs Laterite 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. Peridotite vs Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Laterite. Learn more about Peridotite vs Laterite in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Peridotite and Laterite, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones and that of Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.
More about Peridotite and Laterite
Here you can know more about Peridotite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Laterite consists of mineral content and compound content. The mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Laterite is available in brown, buff, red colors. Appearance of Peridotite is Rough and Shiny and that of Laterite is Rough and Banded. Properties of rock is another aspect for Peridotite vs Laterite. The hardness of Peridotite is 5.5-6 and that of Laterite is 2. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Laterite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite and Laterite is white. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Laterite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Peridotite is heat resistant, pressure resistant, wear resistant whereas Laterite is heat resistant, pressure resistant.
