Conglomerate 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 Conglomerate and Dunite Reserves. Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix. 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.

More about Conglomerate and Dunite

Here you can know more about Conglomerate and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Dunite consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt and mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Dunite, the texture, color and appearance plays an important role in determining the type of rock. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas, Dunite is available in dark greenish - grey colors. Appearance of Conglomerate is Shiny and Rounded and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Conglomerate vs Dunite. The hardness of Conglomerate is 2-3 and that of Dunite is 3.5-4. The types of Conglomerate are Orthoconglomerate and Paraconglomerate whereas types of Dunite are Dunite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate and Dunite is white. The specific heat capacity of Conglomerate is 0.92 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.Conglomerate is heat resistant whereas Dunite is heat resistant, pressure resistant, wear resistant.
