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.

Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.

Lignite vs Diatomite 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 Diatomite Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth. 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 Diatomite information and Lignite vs Diatomite characteristics in the upcoming sections.

More about Lignite and Diatomite

Here you can know more about Lignite and Diatomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Diatomite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Diatomite, 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, Diatomite is available in grey, white, yellow colors. Appearance of Lignite is Veined or Pebbled and that of Diatomite is Soft. Properties of rock is another aspect for Lignite vs Diatomite. Hardness of Lignite and Diatomite is 1. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Diatomite are Not Available. 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 Diatomite is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Diatomite is 0.90 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 Diatomite is heat resistant.
