Formation

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

Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

Laterite vs Lignite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Laterite and Lignite Reserves. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Laterite vs Lignite information and Laterite vs Lignite characteristics in the upcoming sections.

More about Laterite and Lignite

Here you can know more about Laterite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Lignite 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 Lignite includes . You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Laterite is Rough and Banded and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Laterite vs Lignite. The hardness of Laterite is 2 and that of Lignite is 1. The types of Laterite are Laterite whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. 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 Lignite is black. The specific heat capacity of Laterite is 0.92 kJ/Kg K and that of Lignite is 1.26 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 Lignite is heat resistant.
