5 Formation

5.1 Formation

Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.

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.

Mudstone vs Lignite 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 Mudstone and Lignite Reserves. Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. 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 Mudstone vs Lignite information and Mudstone vs Lignite characteristics in the upcoming sections.

Mudstone vs Lignite 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. Mudstone vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mudstone and Properties of Lignite. Learn more about Mudstone vs Lignite in the next section. The interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Mudstone and Lignite, they have various applications in construction industry. The uses of Mudstone in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Lignite include For road aggregate, Steel production.

More about Mudstone and Lignite

Here you can know more about Mudstone and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Lignite consists of mineral content and compound content. The mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Lignite is not available. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Mudstone is Rough and Dull and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Mudstone vs Lignite. The hardness of Mudstone is 2-3 and that of Lignite is 1. The types of Mudstone are Marl, Shale and Argillite whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mudstone is white while that of Lignite is black. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Lignite is 1.26 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Mudstone is heat resistant, impact resistant whereas Lignite is heat resistant.
