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

Foidolite 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. Foidolite vs Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Foidolite and Properties of Laterite. Learn more about Foidolite vs Laterite in the next section. The interior uses of Foidolite 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 Foidolite and Laterite, they have various applications in construction industry. The uses of Foidolite in construction industry include As dimension stone, Cement manufacture, For road aggregate and that of Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.
More about Foidolite and Laterite
Here you can know more about Foidolite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Foidolite and Laterite consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, 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 Foidolite vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Foidolite is available in black, brown, green, grey, pink, white colors whereas, Laterite is available in brown, buff, red colors. Appearance of Foidolite is Dull and that of Laterite is Rough and Banded. Properties of rock is another aspect for Foidolite vs Laterite. The hardness of Foidolite is 1.5 and that of Laterite is 2. The types of Foidolite are Igneous rock 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 Foidolite and Laterite is white. The specific heat capacity of Foidolite 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.Foidolite is heat resistant, wear resistant whereas Laterite is heat resistant, pressure resistant.
