2020-4-28Laterite is a soil and rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock.Tropical weathering lateriation is a prolonged process of chemical weathering which produces
