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

Arkose 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. Arkose vs Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Arkose and Properties of Laterite. Learn more about Arkose vs Laterite in the next section. The interior uses of Arkose include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Arkose and Laterite, they have various applications in construction industry. The uses of Arkose in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar and that of Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.
More about Arkose and Laterite
Here you can know more about Arkose and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Arkose and Laterite consists of mineral content and compound content. The mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, 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 Sedimentary Rocks. When we have to compare Arkose vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Arkose is available in reddish brown colors whereas, Laterite is available in brown, buff, red colors. Appearance of Arkose is Rough and Dull and that of Laterite is Rough and Banded. Properties of rock is another aspect for Arkose vs Laterite. The hardness of Arkose is 6-7 and that of Laterite is 2. The types of Arkose are Not Available whereas types of Laterite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Arkose and Laterite is white. The specific heat capacity of Arkose is Not Available and that of Laterite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Arkose is heat resistant, impact resistant, pressure resistant whereas Laterite is heat resistant, pressure resistant.
