Archaeological Significance
Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
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.

Itacolumite 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. Itacolumite vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Itacolumite and Properties of Lignite. Learn more about Itacolumite vs Lignite in the next section. The interior uses of Itacolumite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens whereas the interior uses of Lignite include . Due to some exceptional properties of Itacolumite and Lignite, they have various applications in construction industry. The uses of Itacolumite in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar and that of Lignite include For road aggregate, Steel production.
More about Itacolumite and Lignite
Here you can know more about Itacolumite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Itacolumite and Lignite consists of mineral content and compound content. The mineral content of Itacolumite includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Lignite includes . You can also check out the list of all Sedimentary Rocks. When we have to compare Itacolumite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Itacolumite is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Itacolumite is Rough and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Itacolumite vs Lignite. The hardness of Itacolumite is 6-7 and that of Lignite is 1. The types of Itacolumite are Sandstone 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 Itacolumite is white while that of Lignite is black. The specific heat capacity of Itacolumite 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.Itacolumite is heat resistant, impact resistant, pressure resistant whereas Lignite is heat resistant.
