Formation

Pyrolite 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.

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

Pyrolite 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 Pyrolite and Syenite Reserves. Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt. 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 Pyrolite vs Syenite information and Pyrolite vs Syenite characteristics in the upcoming sections.

More about Pyrolite and Syenite

Here you can know more about Pyrolite and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyrolite and Syenite consists of mineral content and compound content. The mineral content of Pyrolite 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 Pyrolite vs Syenite, the texture, color and appearance plays an important role in determining the type of rock. Pyrolite is available in dark greenish - grey colors whereas, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Pyrolite is Rough and Shiny and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Pyrolite vs Syenite. Hardness of Pyrolite and Syenite is 5.5-6. The types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite 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 Pyrolite and Syenite is white. The specific heat capacity of Pyrolite 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.Pyrolite is heat resistant, pressure resistant, wear resistant whereas Syenite is heat resistant, impact resistant, wear resistant.
