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 Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Arkose and Laterite Reserves. Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Arkose vs Laterite information and Arkose vs Laterite characteristics in the upcoming sections.
