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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

Lignite vs Turbidite 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 Turbidite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Turbidite. Learn more about Lignite vs Turbidite in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Lignite and Turbidite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Turbidite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement.
More about Lignite and Turbidite
Here you can know more about Lignite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Turbidite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Turbidite, 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, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Lignite is Veined or Pebbled and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Lignite vs Turbidite. The hardness of Lignite is 1 and that of Turbidite is 3. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Turbidite 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 Turbidite is white, greenish white or grey. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Turbidite is 0.92 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 Turbidite is heat resistant.
