Definition
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat
  
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine

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.
  
Norite 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.

Lignite vs Norite 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 Norite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Norite. Learn more about Lignite vs Norite in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Norite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Lignite and Norite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Norite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Lignite and Norite
Here you can know more about Lignite and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Norite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Norite, 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, Norite is available in dark grey to black colors. Appearance of Lignite is Veined or Pebbled and that of Norite is Veined and Shiny. Properties of rock is another aspect for Lignite vs Norite. The hardness of Lignite is 1 and that of Norite is 7. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Norite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Lignite and Norite is black. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Norite is Not Available. 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 Norite is impact resistant, pressure resistant, wear resistant.
