Archaeological Significance
Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
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.

Evaporite 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. Evaporite vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Lignite. Learn more about Evaporite vs Lignite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Lignite include . Due to some exceptional properties of Evaporite and Lignite, they have various applications in construction industry. The uses of Evaporite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Lignite include For road aggregate, Steel production.
More about Evaporite and Lignite
Here you can know more about Evaporite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Lignite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Lignite includes . You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Evaporite is available in green, grey, silver, white colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Evaporite vs Lignite. The hardness of Evaporite is 2-3 and that of Lignite is 1. The types of Evaporite are Sedimentary rock 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 Evaporite is white while that of Lignite is black. The specific heat capacity of Evaporite is 0.92 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.Evaporite is heat resistant, pressure resistant whereas Lignite is heat resistant.
