Formation
Granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

Granite 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. Granite vs Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granite and Properties of Laterite. Learn more about Granite vs Laterite in the next section. The interior uses of Granite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Granite and Laterite, they have various applications in construction industry. The uses of Granite in construction industry include As dimension stone and that of Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.
More about Granite and Laterite
Here you can know more about Granite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granite and Laterite consists of mineral content and compound content. The mineral content of Granite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz 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 Granite vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Granite is available in black, grey, orange, pink, white colors whereas, Laterite is available in brown, buff, red colors. Appearance of Granite is Veined or Pebbled and that of Laterite is Rough and Banded. Properties of rock is another aspect for Granite vs Laterite. The hardness of Granite is 6-7 and that of Laterite is 2. The types of Granite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite, Hybrid Granite, Granodiorite and Alkali Feldspar Granite whereas types of Laterite are Laterite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granite and Laterite is white. The specific heat capacity of Granite is 0.79 kJ/Kg K and that of Laterite 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.Granite is heat resistant, wear resistant whereas Laterite is heat resistant, pressure resistant.
