Archaeological Significance
Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
Marl forms when very fine-grained clay particles are deposited in water which settles at the bottom of water bodies and are compacted by overlying sediment; the water squeezes out and hence forming Marl rock.

Itacolumite vs Marl 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 Marl characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Itacolumite and Properties of Marl. Learn more about Itacolumite vs Marl in the next section. The interior uses of Itacolumite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens whereas the interior uses of Marl include Decorative aggregates and Floor tiles. Due to some exceptional properties of Itacolumite and Marl, 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 Marl include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Itacolumite and Marl
Here you can know more about Itacolumite and Marl. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Itacolumite and Marl consists of mineral content and compound content. The mineral content of Itacolumite includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Itacolumite vs Marl, 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, Marl is available in beige, brown, green, grey, white colors. Appearance of Itacolumite is Rough and that of Marl is Rough and Dull. Properties of rock is another aspect for Itacolumite vs Marl. The hardness of Itacolumite is 6-7 and that of Marl is 2-3. The types of Itacolumite are Sandstone whereas types of Marl are Clay Marl ,Blue Marl, Red Marl, High Bank Marl, Shell Layer Marl, Under Shell Layer Marl, Sand Marl, Green Marl, Grey Marl and Clayey Marl. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Itacolumite and Marl is white. The specific heat capacity of Itacolumite is 0.92 kJ/Kg K and that of Marl is 0.80 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 Marl is heat resistant, impact resistant.
