Archaeological Significance
Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

Laterite vs Phyllite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Laterite vs Phyllite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Laterite and Properties of Phyllite. Learn more about Laterite vs Phyllite in the next section. The interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Phyllite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Laterite and Phyllite, they have various applications in construction industry. The uses of Laterite in construction industry include Cobblestones, For road aggregate, Landscaping, Roadstone and that of Phyllite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar, Roadstone.
More about Laterite and Phyllite
Here you can know more about Laterite and Phyllite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Phyllite 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 Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Phyllite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Phyllite is available in black to grey, light greenish grey colors. Appearance of Laterite is Rough and Banded and that of Phyllite is Crinkled or Wavy. Properties of rock is another aspect for Laterite vs Phyllite. The hardness of Laterite is 2 and that of Phyllite is 1-2. The types of Laterite are Laterite whereas types of Phyllite are Phyllite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite and Phyllite is white. The specific heat capacity of Laterite is 0.92 kJ/Kg K and that of Phyllite 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 Phyllite is heat resistant, pressure resistant, water resistant.
