Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.

Itacolumite vs Diabase 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 Diabase characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Itacolumite and Properties of Diabase. Learn more about Itacolumite vs Diabase in the next section. The interior uses of Itacolumite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens whereas the interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Itacolumite and Diabase, 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 Diabase include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Itacolumite and Diabase
Here you can know more about Itacolumite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Itacolumite and Diabase consists of mineral content and compound content. The mineral content of Itacolumite includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Sedimentary Rocks. When we have to compare Itacolumite vs Diabase, the texture, color and appearance plays an important role in determining the type of rock. Itacolumite is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Diabase is available in dark grey to black colors. Appearance of Itacolumite is Rough and that of Diabase is Vesicular. Properties of rock is another aspect for Itacolumite vs Diabase. The hardness of Itacolumite is 6-7 and that of Diabase is 7. The types of Itacolumite are Not Available whereas types of Diabase are Not Available. 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 Diabase is black. The specific heat capacity of Itacolumite is 0.92 kJ/Kg K and that of Diabase is Not Available. 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 Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
