Archaeological Significance
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.
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Lignite vs Latite 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 Latite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Latite. Learn more about Lignite vs Latite in the next section. The interior uses of Lignite include whereas the interior uses of Latite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Lignite and Latite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Latite 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.
More about Lignite and Latite
Here you can know more about Lignite and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Latite consists of mineral content and compound content. The mineral content of Lignite includes and mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Latite, 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, Latite is available in black, brown, green, grey, pink, white colors. Appearance of Lignite is Veined or Pebbled and that of Latite is Rough. Properties of rock is another aspect for Lignite vs Latite. The hardness of Lignite is 1 and that of Latite is 5-5.5. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Latite are Rhomb porphyries. 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 Latite is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Latite 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 Latite is heat resistant, pressure resistant.
