Laterite has commonly been referred to as a soil type as well as being a rock type. This, and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering), has led to calls for the term to be abandoned altogether. Visa mer Laterite is both a soil and a 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. … Visa mer Tropical weathering (laterization) is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the … Visa mer • Ferricrete – stony particles conglomerated into rock by oxidized iron compounds from ground water • Oxisol – Soil type known for … Visa mer Francis Buchanan-Hamilton first described and named a laterite formation in southern India in 1807.
