Archaeological Significance
Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

Laterite vs Arkose 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 Arkose characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Laterite and Properties of Arkose. Learn more about Laterite vs Arkose in the next section. The interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Arkose include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Laterite and Arkose, they have various applications in construction industry. The uses of Laterite in construction industry include Cobblestones, For road aggregate, Landscaping, Roadstone and that of Arkose include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Laterite and Arkose
Here you can know more about Laterite and Arkose. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Arkose 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 Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Arkose, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Arkose is available in reddish brown colors. Appearance of Laterite is Rough and Banded and that of Arkose is Rough and Dull. Properties of rock is another aspect for Laterite vs Arkose. The hardness of Laterite is 2 and that of Arkose is 6-7. The types of Laterite are Laterite whereas types of Arkose are Arkose. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite and Arkose is white. The specific heat capacity of Laterite is 0.92 kJ/Kg K and that of Arkose is 0.78 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 Arkose is heat resistant, impact resistant, pressure resistant.
