5 Formation

5.1 Formation

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

Norite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Syenite vs Norite 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 Syenite and Norite Reserves. Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals. Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine. 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 Syenite vs Norite information and Syenite vs Norite characteristics in the upcoming sections.

More about Syenite and Norite

Here you can know more about Syenite and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Syenite and Norite consists of mineral content and compound content. The mineral content of Syenite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Syenite vs Norite, the texture, color and appearance plays an important role in determining the type of rock. Syenite is available in brown, buff, cream, green, grey, pink, white colors whereas, Norite is available in dark grey to black colors. Appearance of Syenite is Banded and Foilated and that of Norite is Veined and Shiny. Properties of rock is another aspect for Syenite vs Norite. The hardness of Syenite is 5.5-6 and that of Norite is 7. The types of Syenite are Shonkinite whereas types of Norite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Syenite is white while that of Norite is black. The specific heat capacity of Syenite is 0.92 kJ/Kg K and that of Norite is Not Available.
