Archaeological Significance
Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Itacolumite vs Dolomite 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 Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Itacolumite and Properties of Dolomite. Learn more about Itacolumite vs Dolomite in the next section. The interior uses of Itacolumite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Itacolumite and Dolomite, 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 Dolomite 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, Production of glass and ceramics, Serves as an oil and gas reservoir rock.
More about Itacolumite and Dolomite
Here you can know more about Itacolumite and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Itacolumite and Dolomite consists of mineral content and compound content. The mineral content of Itacolumite includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Itacolumite vs Dolomite, 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, Dolomite is available in black, brown, green, grey, pink, white colors. Appearance of Itacolumite is Rough and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Itacolumite vs Dolomite. The hardness of Itacolumite is 6-7 and that of Dolomite is 3.5-4. The types of Itacolumite are Sandstone whereas types of Dolomite are Boninite and Jasperoid. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Itacolumite and Dolomite is white. The specific heat capacity of Itacolumite is 0.92 kJ/Kg K and that of Dolomite 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.Itacolumite is heat resistant, impact resistant, pressure resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
