Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

Laterite vs Anthracite 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 Anthracite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Laterite and Properties of Anthracite. Learn more about Laterite vs Anthracite in the next section. The interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Anthracite include Not yet used. Due to some exceptional properties of Laterite and Anthracite, they have various applications in construction industry. The uses of Laterite in construction industry include Cobblestones, For road aggregate, Landscaping, Roadstone and that of Anthracite include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Laterite and Anthracite
Here you can know more about Laterite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Anthracite 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 Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Laterite is Rough and Banded and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Laterite vs Anthracite. The hardness of Laterite is 2 and that of Anthracite is 1-1.5. The types of Laterite are Not Available whereas types of Anthracite are Semi-anthracite and Meta-anthracite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite is white while that of Anthracite is black. The specific heat capacity of Laterite is Not Available and that of Anthracite is 1.32 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 Anthracite is heat resistant, water resistant.
