Archaeological Significance
Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

Scoria 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. Scoria vs Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Scoria and Properties of Laterite. Learn more about Scoria vs Laterite in the next section. The interior uses of Scoria 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 Scoria and Laterite, they have various applications in construction industry. The uses of Scoria in construction industry include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works and that of Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.
More about Scoria and Laterite
Here you can know more about Scoria and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Laterite consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica 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 Scoria vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Laterite is available in brown, buff, red colors. Appearance of Scoria is Glassy and Vesicular and that of Laterite is Rough and Banded. Properties of rock is another aspect for Scoria vs Laterite. The hardness of Scoria is 5-6 and that of Laterite is 2. The types of Scoria are Basaltic Scoria and Andesitic Scoria 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 Scoria and Laterite is white. The specific heat capacity of Scoria is 0.84 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.Scoria is heat resistant, impact resistant, pressure resistant, wear resistant whereas Laterite is heat resistant, pressure resistant.
