Archaeological Significance
Formation
Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

Siltstone vs Laterite 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. Siltstone vs Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Siltstone and Properties of Laterite. Learn more about Siltstone vs Laterite in the next section. The interior uses of Siltstone include Decorative aggregates and Interior decoration whereas the interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Siltstone and Laterite, they have various applications in construction industry. The uses of Siltstone in construction industry include Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.
More about Siltstone and Laterite
Here you can know more about Siltstone and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Siltstone and Laterite consists of mineral content and compound content. The mineral content of Siltstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt 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 Sedimentary Rocks. When we have to compare Siltstone vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Siltstone is available in brown, red, reddish brown colors whereas, Laterite is available in brown, buff, red colors. Appearance of Siltstone is Rough and that of Laterite is Rough and Banded. Properties of rock is another aspect for Siltstone vs Laterite. The hardness of Siltstone is 6-7 and that of Laterite is 2. The types of Siltstone are Siltstone 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 Siltstone and Laterite is white. The specific heat capacity of Siltstone 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.Siltstone is heat resistant, impact resistant, pressure resistant, water resistant whereas Laterite is heat resistant, pressure resistant.
