Archaeological Significance
Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

More about Itacolumite and Oolite
Here you can know more about Itacolumite and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Itacolumite and Oolite consists of mineral content and compound content. The mineral content of Itacolumite includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Sedimentary Rocks. When we have to compare Itacolumite vs Oolite, 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, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Itacolumite is Rough and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Itacolumite vs Oolite. The hardness of Itacolumite is 6-7 and that of Oolite is 3-4. The types of Itacolumite are Sandstone whereas types of Oolite are Pisolitic Oolite and Oncolitic Oolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Itacolumite and Oolite is white. The specific heat capacity of Itacolumite is 0.92 kJ/Kg K and that of Oolite is 0.65 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 Oolite is heat resistant, wear resistant.
