Definition
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat
  
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

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.
  
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

Lignite vs Suevite 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 Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Suevite. Learn more about Lignite vs Suevite in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Lignite and Suevite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Lignite and Suevite
Here you can know more about Lignite and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Suevite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Suevite, 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, Suevite is available in black, brown, colourless, green, grey, pink colors. Appearance of Lignite is Veined or Pebbled and that of Suevite is Banded. Properties of rock is another aspect for Lignite vs Suevite. The hardness of Lignite is 1 and that of Suevite is 5.5. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Suevite are Phyllosilicates, Calcite. 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 Suevite is light to dark brown. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Suevite is 0.92 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 Suevite is heat resistant.
