5 Formation

5.1 Formation

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

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.

Serpentinite 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 Serpentinite and Lignite Reserves. A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.. 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 Serpentinite vs Lignite information and Serpentinite vs Lignite characteristics in the upcoming sections.

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

More about Serpentinite and Lignite

Here you can know more about Serpentinite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Lignite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Lignite is not available. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, colourless, green, grey, white colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Serpentinite is Rough and Dull and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Serpentinite vs Lignite. The hardness of Serpentinite is 3-5 and that of Lignite is 1. The types of Serpentinite are Jadeitite 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 Serpentinite is white, greenish white or grey while that of Lignite is black. The specific heat capacity of Serpentinite is 0.95 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.Serpentinite is heat resistant whereas Lignite is heat resistant.
