Formation

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 is a type of sedimentary rock which is generally a reddish weathering product of basalt.

More about Anthracite and Laterite

Here you can know more about Anthracite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Laterite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals 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 Metamorphic Rocks. When we have to compare Anthracite vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Laterite is available in brown, buff, red colors. Appearance of Anthracite is Veined or Pebbled and that of Laterite is Rough and Banded. Properties of rock is another aspect for Anthracite vs Laterite. The hardness of Anthracite is 1-1.5 and that of Laterite is 2. The types of Anthracite are Semi-anthracite and Meta-anthracite 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 Anthracite is black while that of Laterite is white. The specific heat capacity of Anthracite is 1.32 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.Anthracite is heat resistant, water resistant whereas Laterite is heat resistant, pressure resistant.
