5 Formation

5.1 Formation

Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Dolomite 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 Dolomite and Syenite Reserves. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. 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 Dolomite vs Syenite information and Dolomite vs Syenite characteristics in the upcoming sections.

More about Dolomite and Syenite

Here you can know more about Dolomite and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Syenite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides 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 Sedimentary Rocks. When we have to compare Dolomite vs Syenite, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Dolomite is Glassy or Pearly and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Dolomite vs Syenite. The hardness of Dolomite is 3.5-4 and that of Syenite is 5.5-6. The types of Dolomite are Boninite and Jasperoid 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 Dolomite and Syenite is white. The specific heat capacity of Dolomite is 0.92 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.Dolomite is heat resistant, pressure resistant, wear resistant whereas Syenite is heat resistant, impact resistant, wear resistant.
