Definition
Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Formation
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.
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 vs Lignite 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. Granodiorite vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granodiorite and Properties of Lignite. Learn more about Granodiorite vs Lignite in the next section. The interior uses of Granodiorite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Stair treads whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Granodiorite and Lignite, they have various applications in construction industry. The uses of Granodiorite in construction industry include As dimension stone and that of Lignite include For road aggregate, Steel production.
More about Granodiorite and Lignite
Here you can know more about Granodiorite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Lignite consists of mineral content and compound content. The mineral content of Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Lignite is not available. You can also check out the list of all Igneous Rocks. When we have to compare Granodiorite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Granodiorite is available in black, grey, orange, pink, white colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Granodiorite is Veined or Pebbled and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Granodiorite vs Lignite. The hardness of Granodiorite is 6 and that of Lignite is 1. The types of Granodiorite are Not Available whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granodiorite is white while that of Lignite is black. The specific heat capacity of Granodiorite is 0.79 kJ/Kg K and that of Lignite is 1.26 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granodiorite is heat resistant, wear resistant whereas Lignite is heat resistant.
