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.

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

Lignite vs Limestone 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 Limestone Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. 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 Limestone information and Lignite vs Limestone characteristics in the upcoming sections.

Lignite vs Limestone 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 Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Limestone. Learn more about Lignite vs Limestone in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Lignite and Limestone, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Limestone include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium.

More about Lignite and Limestone

Here you can know more about Lignite and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Limestone consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all . When we have to compare Lignite vs Limestone, 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, Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. Appearance of Lignite is Veined or Pebbled and that of Limestone is Rough and Banded. Properties of rock is another aspect for Lignite vs Limestone. The hardness of Lignite is 1 and that of Limestone is 3-4. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. 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 Limestone is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Limestone is 0.91 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 Limestone is pressure resistant.
