Definition
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism

Archaeological Significance
Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.

More about Laterite and Greenschist
Here you can know more about Laterite and Greenschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Greenschist 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 Greenschist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Serpentine, Sillimanite, Staurolite, Talc. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Greenschist, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Greenschist is available in dark greenish - grey, green colors. Appearance of Laterite is Rough and Banded and that of Greenschist is Layered and Shiny. Properties of rock is another aspect for Laterite vs Greenschist. The hardness of Laterite is 2 and that of Greenschist is 3.5-4. The types of Laterite are Laterite whereas types of Greenschist are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite and Greenschist is white. The specific heat capacity of Laterite is 0.92 kJ/Kg K and that of Greenschist 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 Greenschist is impact resistant, pressure resistant, water resistant.
