Formation

Formation
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.   
Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

Dunite vs Mugearite 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 Mugearite Reserves. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides. 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 Mugearite information and Dunite vs Mugearite characteristics in the upcoming sections.

More about Dunite and Mugearite

Here you can know more about Dunite and Mugearite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dunite and Mugearite 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 Mugearite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Dunite vs Mugearite, the texture, color and appearance plays an important role in determining the type of rock. Dunite is available in dark greenish - grey colors whereas, Mugearite is available in black, brown, light to dark grey colors. Appearance of Dunite is Rough and Shiny and that of Mugearite is Dull and Soft. Properties of rock is another aspect for Dunite vs Mugearite. The hardness of Dunite is 3.5-4 and that of Mugearite is 6. The types of Dunite are Not Available whereas types of Mugearite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dunite is white while that of Mugearite is white to grey. The specific heat capacity of Dunite is 1.25 kJ/Kg K and that of Mugearite is 0.84 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 Mugearite is heat resistant, pressure resistant, wear resistant.
