Epidosite vs Itacolumite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Epidosite and Itacolumite Reserves. Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt. A yellow sandstone which is flexible when cut into thin strips. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Epidosite vs Itacolumite information and Epidosite vs Itacolumite characteristics in the upcoming sections.

Epidosite vs Itacolumite 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. Epidosite vs Itacolumite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Epidosite and Properties of Itacolumite. Learn more about Epidosite vs Itacolumite in the next section. The interior uses of Epidosite include Decorative aggregates, Floor tiles, Homes, Hotels and Interior decoration whereas the interior uses of Itacolumite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Epidosite and Itacolumite, they have various applications in construction industry. The uses of Epidosite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Itacolumite include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.

More about Epidosite and Itacolumite

Here you can know more about Epidosite and Itacolumite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Epidosite and Itacolumite consists of mineral content and compound content. The mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene and mineral content of Itacolumite includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Epidosite vs Itacolumite, the texture, color and appearance plays an important role in determining the type of rock. Epidosite is available in black, brown, light to dark grey colors whereas, Itacolumite is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Epidosite is Dull and Soft and that of Itacolumite is Rough. Properties of rock is another aspect for Epidosite vs Itacolumite. The hardness of Epidosite is 6 and that of Itacolumite is 6-7. The types of Epidosite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite whereas types of Itacolumite are Sandstone. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Epidosite is white to grey while that of Itacolumite is white. The specific heat capacity of Epidosite is 0.84 kJ/Kg K and that of Itacolumite 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.Epidosite is heat resistant, pressure resistant, wear resistant whereas Itacolumite is heat resistant, impact resistant, pressure resistant.
