Every rock is composed of one or more minerals. Laterite composition which can be further divided into mineral and compound content. The Laterite mineral content includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene.
Its compound content includes Aluminium Oxide, CaO, Iron(III) Oxide, FeO, Potassium Oxide, MgO, MnO, Sodium Oxide, Phosphorus Pentoxide, Silicon Dioxide, Titanium Dioxide. You can also check out Properties of Laterite.
Transformation of Laterite
Every rock on earth undergoes transformation process. Laterite is a type of Sedimentary Rocks. Transformation of Laterite takes place in three steps- Metamorphism, Weathering and Erosion.
- Metamorphism of Laterite:- Metamorphism is change in arrangement of minerals and texture in the pre-existing rocks. Laterite rock does not undergo metamorphism. Unlike in formation of Laterite, the rock does not melt into liquid magma.
- Weathering of Laterite:- The breaking down of rocks when they come in contact with the Earth's atmosphere, ecology and water is called as weathering. Talking about weathering of Laterite, this rock undergoes weathering. Weathering of Igneous rocks leads to formation of Sedimentary rocks. Weathering is further classified as chemical and mechanical weathering. Laterite undergoes biological weathering and chemical weathering.
- Laterite Erosion:- After formation of Laterite, let’s move on to Laterite Erosion. The weathered small fragments of rock are carried from one place to other by a process called erosion. Laterite rock undergoes Erosion. Erosion is one of the important aspects in the life cycle of a rock. Laterite undergoes chemical erosion, water erosion and wind erosion.
