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.
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

Lignite vs Granodiorite 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 Granodiorite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Granodiorite. Learn more about Lignite vs Granodiorite in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Granodiorite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Stair treads. Due to some exceptional properties of Lignite and Granodiorite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Granodiorite include As dimension stone.
More about Lignite and Granodiorite
Here you can know more about Lignite and Granodiorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Granodiorite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Granodiorite, 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, Granodiorite is available in black, grey, orange, pink, white colors. Appearance of Lignite is Veined or Pebbled and that of Granodiorite is Veined or Pebbled. Properties of rock is another aspect for Lignite vs Granodiorite. The hardness of Lignite is 1 and that of Granodiorite is 6. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Granodiorite 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 Granodiorite is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Granodiorite is 0.79 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 Granodiorite is heat resistant, wear resistant.
