Definition
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface

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.
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Lignite vs Basaltic Trachyandesite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Basaltic Trachyandesite. Learn more about Lignite vs Basaltic Trachyandesite in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Basaltic Trachyandesite include Floor tiles, Homes, Hotels and Kitchens. Due to some exceptional properties of Lignite and Basaltic Trachyandesite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Basaltic Trachyandesite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Lignite and Basaltic Trachyandesite
Here you can know more about Lignite and Basaltic Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Basaltic Trachyandesite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Basaltic 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, Basaltic Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Lignite is Veined or Pebbled and that of Basaltic Trachyandesite is Dull and Soft. Properties of rock is another aspect for Lignite vs Basaltic Trachyandesite. The hardness of Lignite is 1 and that of Basaltic Trachyandesite is 6. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. 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 Basaltic Trachyandesite is white to grey. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Basaltic 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 Basaltic Trachyandesite is heat resistant, pressure resistant, wear resistant.
