Formation

Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

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

Aplite 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 Aplite and Syenite Reserves. Aplite is a fine-grained granite composed mainly of feldspar and quartz. 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 Aplite vs Syenite information and Aplite vs Syenite characteristics in the upcoming sections.

More about Aplite and Syenite

Here you can know more about Aplite and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Syenite consists of mineral content and compound content. The mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz 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 Aplite vs Syenite, the texture, color and appearance plays an important role in determining the type of rock. Aplite is available in black, grey, orange, pink, white colors whereas, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Aplite is Veined or Pebbled and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Aplite vs Syenite. The hardness of Aplite is 6.5 and that of Syenite is 5.5-6. The types of Aplite are Igneous rock 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 Aplite and Syenite is white. The specific heat capacity of Aplite is 0.79 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.Aplite is heat resistant, wear resistant whereas Syenite is heat resistant, impact resistant, wear resistant.
