Definition

Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

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.

Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

Lignite vs Boninite 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 Boninite Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction. 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 Boninite information and Lignite vs Boninite characteristics in the upcoming sections.

Lignite vs Boninite 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 Boninite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Boninite. Learn more about Lignite vs Boninite in the next section. The interior uses of Lignite include whereas the interior uses of Boninite include Decorative aggregates, Homes and Kitchens. Due to some exceptional properties of Lignite and Boninite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Boninite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Lignite and Boninite

Here you can know more about Lignite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Boninite consists of mineral content and compound content. The mineral content of Lignite includes and mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Boninite, 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, Boninite is available in bluish - grey, brown, green, grey colors. Appearance of Lignite is Veined or Pebbled and that of Boninite is Dull and Soft. Properties of rock is another aspect for Lignite vs Boninite. The hardness of Lignite is 1 and that of Boninite is 7. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Boninite are Basalt. 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 Boninite is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Boninite is 0.84 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 Boninite is heat resistant, impact resistant, pressure resistant, wear resistant.
