Definition
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas
Litchfieldite is a rare igneous rock which is coarse-grained, foliated and a variety of nepheline syenite, sometimes also called as nepheline syenite gneiss or gneissic nepeheline syenite

Archaeological Significance
Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Litchfieldite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Laterite and Litchfieldite
Here you can know more about Laterite and Litchfieldite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Litchfieldite 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 Litchfieldite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Litchfieldite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Litchfieldite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Laterite is Rough and Banded and that of Litchfieldite is Banded and Foilated. Properties of rock is another aspect for Laterite vs Litchfieldite. The hardness of Laterite is 2 and that of Litchfieldite is 5.5-6. The types of Laterite are Laterite whereas types of Litchfieldite are Borolanite and Litchfieldite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite and Litchfieldite is white. The specific heat capacity of Laterite is 0.92 kJ/Kg K and that of Litchfieldite is 0.79 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 Litchfieldite is heat resistant, impact resistant, wear resistant.
