Archaeological Significance
Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

Laterite vs Aplite 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 Aplite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Laterite and Properties of Aplite. Learn more about Laterite vs Aplite in the next section. The interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Laterite and Aplite, they have various applications in construction industry. The uses of Laterite in construction industry include Cobblestones, For road aggregate, Landscaping, Roadstone and that of Aplite include As dimension stone.
More about Laterite and Aplite
Here you can know more about Laterite and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Aplite 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 Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Aplite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Aplite is available in black, grey, orange, pink, white colors. Appearance of Laterite is Rough and Banded and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Laterite vs Aplite. The hardness of Laterite is 2 and that of Aplite is 6.5. The types of Laterite are Laterite whereas types of Aplite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite and Aplite is white. The specific heat capacity of Laterite is 0.92 kJ/Kg K and that of Aplite 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 Aplite is heat resistant, wear resistant.
