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.

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 . 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.
