Formation
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

More about Andesite and Laterite
Here you can know more about Andesite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Andesite and Laterite consists of mineral content and compound content. The mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon and mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Andesite vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Andesite is available in bluish - grey, grey, pink, yellow colors whereas, Laterite is available in brown, buff, red colors. Appearance of Andesite is Dull and Soft and that of Laterite is Rough and Banded. Properties of rock is another aspect for Andesite vs Laterite.
