Definition
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Tachylite 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 Tachylite 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 Tachylite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Laterite and Properties of Tachylite. Learn more about Laterite vs Tachylite in the next section. The interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Tachylite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Laterite and Tachylite, they have various applications in construction industry. The uses of Laterite in construction industry include Cobblestones, For road aggregate, Landscaping, Roadstone and that of Tachylite include Cutting tool, Knives, Landscaping, Scrapers.
More about Laterite and Tachylite
Here you can know more about Laterite and Tachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Tachylite 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 Tachylite includes Feldspar, Olivine. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Tachylite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Tachylite is available in black, dark brown colors. Appearance of Laterite is Rough and Banded and that of Tachylite is Glassy. Properties of rock is another aspect for Laterite vs Tachylite. The hardness of Laterite is 2 and that of Tachylite is 5.5. The types of Laterite are Not Available whereas types of Tachylite are Not Available. 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 Tachylite is vermilion. The specific heat capacity of Laterite is Not Available and that of Tachylite is 0.56 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 Tachylite is heat resistant, impact resistant, wear resistant.
