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.
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.

Lignite vs Jasperoid 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 Jasperoid characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Jasperoid. Learn more about Lignite vs Jasperoid in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Jasperoid include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Lignite and Jasperoid, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Jasperoid 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, Production of glass and ceramics, Serves as an oil and gas reservoir rock.
More about Lignite and Jasperoid
Here you can know more about Lignite and Jasperoid. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Jasperoid consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Jasperoid, 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, Jasperoid is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Lignite is Veined or Pebbled and that of Jasperoid is Glassy or Pearly. Properties of rock is another aspect for Lignite vs Jasperoid. The hardness of Lignite is 1 and that of Jasperoid is 3.5-4. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Jasperoid are Not Available. 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 Jasperoid is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Jasperoid 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 Jasperoid is heat resistant, pressure resistant, wear resistant.
