Definition
Granophyre is a type of granitic rock which consists of intergrown feldspar and quartz crystals in a medium to fine grained groundmass
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Formation
Granophyre is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive 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.

Granophyre 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. Granophyre vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granophyre and Properties of Lignite. Learn more about Granophyre vs Lignite in the next section. The interior uses of Granophyre include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Granophyre and Lignite, they have various applications in construction industry. The uses of Granophyre in construction industry include As dimension stone and that of Lignite include For road aggregate, Steel production.
More about Granophyre and Lignite
Here you can know more about Granophyre and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granophyre and Lignite consists of mineral content and compound content. The mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, 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 Granophyre vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Granophyre 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 Granophyre is Veined or Pebbled and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Granophyre vs Lignite. The hardness of Granophyre is 6-7 and that of Lignite is 1. The types of Granophyre 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 Granophyre is white while that of Lignite is black. The specific heat capacity of Granophyre 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.Granophyre is heat resistant, wear resistant whereas Lignite is heat resistant.
