Formation

Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

Dunite vs Conglomerate 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 Dunite and Conglomerate Reserves. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix. 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 Dunite vs Conglomerate information and Dunite vs Conglomerate characteristics in the upcoming sections.

More about Dunite and Conglomerate

Here you can know more about Dunite and Conglomerate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dunite and Conglomerate consists of mineral content and compound content. The mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Conglomerate includes Clay, Sand, Silica, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Dunite vs Conglomerate, the texture, color and appearance plays an important role in determining the type of rock. Dunite is available in dark greenish - grey colors whereas, Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. Appearance of Dunite is Rough and Shiny and that of Conglomerate is Shiny and Rounded. Properties of rock is another aspect for Dunite vs Conglomerate. The hardness of Dunite is 3.5-4 and that of Conglomerate is 2-3. The types of Dunite are Dunite whereas types of Conglomerate are Orthoconglomerate and Paraconglomerate. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dunite and Conglomerate is white. The specific heat capacity of Dunite is 1.25 kJ/Kg K and that of Conglomerate 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.Dunite is heat resistant, pressure resistant, wear resistant whereas Conglomerate is heat resistant.
