Formation

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

Lignite vs Laterite 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 Lignite and Laterite Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. 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 Lignite vs Laterite information and Lignite vs Laterite characteristics in the upcoming sections.

Lignite 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. Lignite vs Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Laterite. Learn more about Lignite vs Laterite in the next section. The interior uses of Lignite include whereas the interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Lignite and Laterite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.

More about Lignite and Laterite

Here you can know more about Lignite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Laterite consists of mineral content and compound content. The mineral content of Lignite includes 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 Lignite vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Lignite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Laterite is available in brown, buff, red colors. Appearance of Lignite is Veined or Pebbled and that of Laterite is Rough and Banded. Properties of rock is another aspect for Lignite vs Laterite. The hardness of Lignite is 1 and that of Laterite is 2. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite 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 Lignite is black while that of Laterite is white. The specific heat capacity of Lignite is 1.26 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.Lignite is heat resistant whereas Laterite is heat resistant, pressure resistant.
