Definition

Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas

Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

Formation

Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

Laterite vs Adakite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Laterite and Adakite Reserves. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Laterite vs Adakite information and Laterite vs Adakite characteristics in the upcoming sections.

More about Laterite and Adakite

Here you can know more about Laterite and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Adakite 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 Adakite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Adakite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Adakite is available in black, brown, light to dark grey colors. Appearance of Laterite is Rough and Banded and that of Adakite is Dull and Soft. Properties of rock is another aspect for Laterite vs Adakite. The hardness of Laterite is 2 and that of Adakite is 3-4. The types of Laterite are Laterite whereas types of Adakite are Intermediate volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite is white while that of Adakite is bluish black. The specific heat capacity of Laterite is 0.92 kJ/Kg K and that of Adakite is 0.84 kJ/Kg K. 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 Adakite is heat resistant, pressure resistant, wear resistant.
