Definition
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas
Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt

Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
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 vs Siltstone 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 Siltstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Laterite and Properties of Siltstone. Learn more about Laterite vs Siltstone in the next section. The interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Siltstone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Laterite and Siltstone, they have various applications in construction industry. The uses of Laterite in construction industry include Cobblestones, For road aggregate, Landscaping, Roadstone and that of Siltstone include Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Laterite and Siltstone
Here you can know more about Laterite and Siltstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Siltstone 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 Siltstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Siltstone, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Siltstone is available in brown, red, reddish brown colors. Appearance of Laterite is Rough and Banded and that of Siltstone is Rough. Properties of rock is another aspect for Laterite vs Siltstone. The hardness of Laterite is 2 and that of Siltstone is 6-7. The types of Laterite are Not Available whereas types of Siltstone are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite and Siltstone is white. The specific heat capacity of Laterite is Not Available and that of Siltstone is Not Available. 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 Siltstone is heat resistant, impact resistant, pressure resistant, water resistant.
