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.

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.

Lignite vs Mudstone 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 Mudstone Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. 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. 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 Mudstone information and Lignite vs Mudstone characteristics in the upcoming sections.

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

More about Lignite and Mudstone

Here you can know more about Lignite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Mudstone consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Mudstone, 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, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Lignite is Veined or Pebbled and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Lignite vs Mudstone. The hardness of Lignite is 1 and that of Mudstone is 2-3. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Mudstone are Marl, Shale and Argillite. 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 Mudstone is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Mudstone is 0.39 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 Mudstone is heat resistant, impact resistant.
