Marble vs Dunite 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 Marble and Dunite Reserves. Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. 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 Marble vs Dunite information and Marble vs Dunite characteristics in the upcoming sections.

More about Marble and Dunite

Here you can know more about Marble and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marble and Dunite consists of mineral content and compound content. The mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz and mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Marble vs Dunite, the texture, color and appearance plays an important role in determining the type of rock. Marble is available in black, blue, brown, grey, pink, white colors whereas, Dunite is available in dark greenish - grey colors. Appearance of Marble is Veined and Shiny and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Marble vs Dunite. The hardness of Marble is 3-4 and that of Dunite is 3.5-4. The types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble whereas types of Dunite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Marble and Dunite is white. The specific heat capacity of Marble is 0.88 kJ/Kg K and that of Dunite is 1.25 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Marble is heat resistant whereas Dunite is heat resistant, pressure resistant, wear resistant.
