Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Itacolumite vs Granulite 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 Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Itacolumite and Properties of Granulite. Learn more about Itacolumite vs Granulite in the next section. The interior uses of Itacolumite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Itacolumite and Granulite, 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 Granulite include As dimension stone, Building houses or walls.
More about Itacolumite and Granulite
Here you can know more about Itacolumite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Itacolumite and Granulite consists of mineral content and compound content. The mineral content of Itacolumite includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Itacolumite vs Granulite, 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, Granulite is available in black, brown colors. Appearance of Itacolumite is Rough and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Itacolumite vs Granulite. Hardness of Itacolumite and Granulite is 6-7. The types of Itacolumite are Sandstone whereas types of Granulite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Itacolumite and Granulite is white. The specific heat capacity of Itacolumite is 0.92 kJ/Kg K and that of Granulite is 0.14 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 Granulite is heat resistant, wear resistant.
