Formation
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.
  
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.

Anthracite vs Itacolumite 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. Anthracite vs Itacolumite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anthracite and Properties of Itacolumite. Learn more about Anthracite vs Itacolumite in the next section. The interior uses of Anthracite include Not yet used whereas the interior uses of Itacolumite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Anthracite and Itacolumite, they have various applications in construction industry. The uses of Anthracite in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production and that of Itacolumite include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Anthracite and Itacolumite
Here you can know more about Anthracite and Itacolumite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Itacolumite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Itacolumite includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Itacolumite, the texture, color and appearance plays an important role in determining the type of rock. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Itacolumite is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Anthracite is Veined or Pebbled and that of Itacolumite is Rough. Properties of rock is another aspect for Anthracite vs Itacolumite. The hardness of Anthracite is 1-1.5 and that of Itacolumite is 6-7. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Itacolumite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anthracite is black while that of Itacolumite is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Itacolumite 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.Anthracite is heat resistant, water resistant whereas Itacolumite is heat resistant, impact resistant, pressure resistant.
