Formation

Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

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

Amphibolite vs Laterite 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 Amphibolite and Laterite Reserves. Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. 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 Amphibolite vs Laterite information and Amphibolite vs Laterite characteristics in the upcoming sections.

More about Amphibolite and Laterite

Here you can know more about Amphibolite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Amphibolite and Laterite consists of mineral content and compound content. The mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite 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 Amphibolite vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Amphibolite is available in black, brown, green, grey colors whereas, Laterite is available in brown, buff, red colors. Appearance of Amphibolite is Foliated and that of Laterite is Rough and Banded. Properties of rock is another aspect for Amphibolite vs Laterite. The hardness of Amphibolite is 6-7 and that of Laterite is 2. The types of Amphibolite are Hornblendite whereas types of Laterite are Laterite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Amphibolite is white to grey while that of Laterite is white. The specific heat capacity of Amphibolite is 0.84 kJ/Kg K and that of Laterite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Amphibolite is heat resistant, pressure resistant, wear resistant whereas Laterite is heat resistant, pressure resistant.
