5 Formation

5.1 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.

Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

Lignite vs Andesite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Lignite and Andesite Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Lignite vs Andesite information and Lignite vs Andesite characteristics in the upcoming sections.

Lignite vs Andesite 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 Andesite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Andesite. Learn more about Lignite vs Andesite in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Andesite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Lignite and Andesite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Andesite include Cobblestones, Construction aggregate, For road aggregate.

More about Lignite and Andesite

Here you can know more about Lignite and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Andesite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Andesite, 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, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Lignite is Veined or Pebbled and that of Andesite is Dull and Soft. Properties of rock is another aspect for Lignite vs Andesite. The hardness of Lignite is 1 and that of Andesite is 7. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Andesite are Icelandite. 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 Andesite is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Andesite is 2.39 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 Andesite is heat resistant, pressure resistant, wear resistant.
