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.
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

Lignite vs Jaspillite 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 Jaspillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Jaspillite. Learn more about Lignite vs Jaspillite in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Jaspillite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Lignite and Jaspillite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Jaspillite 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 Jaspillite
Here you can know more about Lignite and Jaspillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Jaspillite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Jaspillite includes Coesite, Quartz, Sand. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Jaspillite, 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, Jaspillite is available in red, reddish brown colors. Appearance of Lignite is Veined or Pebbled and that of Jaspillite is Banded and Glassy. Properties of rock is another aspect for Lignite vs Jaspillite. The hardness of Lignite is 1 and that of Jaspillite is 3. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type. 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 Jaspillite is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Jaspillite is 3.20 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 Jaspillite is heat resistant, impact resistant, wear resistant.
