Definition
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished

Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

More about Laterite and Appinite
Here you can know more about Laterite and Appinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Appinite consists of mineral content and compound content. The mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene and mineral content of Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Appinite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Laterite is Rough and Banded and that of Appinite is Dull, Banded and Foilated. Properties of rock is another aspect for Laterite vs Appinite. The hardness of Laterite is 2 and that of Appinite is 5-6. The types of Laterite are Not Available whereas types of Appinite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite and Appinite is white. The specific heat capacity of Laterite is Not Available and that of Appinite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Laterite is heat resistant, pressure resistant whereas Appinite is heat resistant, impact resistant.
