Archaeological Significance
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.
Monzonite 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 Monzonite 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 Monzonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Monzonite. Learn more about Lignite vs Monzonite in the next section. The interior uses of Lignite include whereas the interior uses of Monzonite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Lignite and Monzonite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Monzonite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.
More about Lignite and Monzonite
Here you can know more about Lignite and Monzonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Monzonite consists of mineral content and compound content. The mineral content of Lignite includes and mineral content of Monzonite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Monzonite, 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, Monzonite is available in black, brown, light to dark grey, white colors. Appearance of Lignite is Veined or Pebbled and that of Monzonite is Shiny. Properties of rock is another aspect for Lignite vs Monzonite. The hardness of Lignite is 1 and that of Monzonite is 6-7. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Monzonite are Quartz Monzonite, Mangerite, Syenite and Diorite. 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 Monzonite is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Monzonite 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 Monzonite is heat resistant, impact resistant, pressure resistant.
