5.1 Formation
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Dunite vs Syenite 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 Syenite Reserves. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals. 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 Syenite information and Dunite vs Syenite characteristics in the upcoming sections.

Dunite vs Syenite 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. Dunite vs Syenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dunite and Properties of Syenite. Learn more about Dunite vs Syenite in the next section. The interior uses of Dunite include Decorative aggregates and Interior decoration whereas the interior uses of Syenite include Flooring, Homes, Hotels and Interior decoration. Due to some exceptional properties of Dunite and Syenite, they have various applications in construction industry. The uses of Dunite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Syenite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Dunite and Syenite

Here you can know more about Dunite and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dunite and Syenite 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 Syenite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Dunite vs Syenite, the texture, color and appearance plays an important role in determining the type of rock. Dunite is available in dark greenish - grey colors whereas, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Dunite is Rough and Shiny and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Dunite vs Syenite. The hardness of Dunite is 3.5-4 and that of Syenite is 5.5-6. The types of Dunite are Not Available whereas types of Syenite are Shonkinite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dunite and Syenite is white. The specific heat capacity of Dunite is 1.25 kJ/Kg K and that of Syenite 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 Syenite is heat resistant, impact resistant, wear resistant.
