5 Formation

5.1 Formation

When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

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

Tonalite 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 Tonalite and Syenite Reserves. Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture. 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 Tonalite vs Syenite information and Tonalite vs Syenite characteristics in the upcoming sections.

The uses of Tonalite in construction industry include As dimension stone, Cement manufacture, Cobblestones, Construction aggregate, For road aggregate 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 Tonalite and Syenite

Here you can know more about Tonalite and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tonalite and Syenite consists of mineral content and compound content. The mineral content of Tonalite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Manganese Oxides, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon 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 Tonalite vs Syenite, the texture, color and appearance plays an important role in determining the type of rock. Tonalite is available in black, brown, light to dark grey, white colors whereas, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Tonalite is Banded and Foilated and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Tonalite vs Syenite. The hardness of Tonalite is 6-7 and that of Syenite is 5.5-6. The types of Tonalite are Dacite 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 Tonalite is bluish black while that of Syenite is white. The specific heat capacity of Tonalite 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.Tonalite is heat resistant, pressure resistant, water resistant whereas Syenite is heat resistant, impact resistant, wear resistant.
