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.

Trachyandesite 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.

More about Lignite and Trachyandesite

Here you can know more about Lignite and Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Trachyandesite consists of mineral content and compound content. The mineral content of Lignite includes and mineral content of Trachyandesite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Trachyandesite, 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, Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Lignite is Veined or Pebbled and that of Trachyandesite is Dull and Soft. Properties of rock is another aspect for Lignite vs Trachyandesite. The hardness of Lignite is 1 and that of Trachyandesite is 4-5. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Trachyandesite are Basaltic Trachyandesite. 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 Trachyandesite is light to dark brown. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Trachyandesite is 0.84 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 Trachyandesite is heat resistant, pressure resistant, wear resistant.
