Definition
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

Formation
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Pantellerite 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 Pantellerite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Syenite vs Pantellerite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Syenite and Properties of Pantellerite. Learn more about Syenite vs Pantellerite in the next section. The interior uses of Syenite include Flooring, Homes, Hotels and Interior decoration whereas the interior uses of Pantellerite include Not yet used. Due to some exceptional properties of Syenite and Pantellerite, they have various applications in construction industry. The uses of Syenite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Pantellerite include Na.
More about Syenite and Pantellerite
Here you can know more about Syenite and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Syenite and Pantellerite 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 Pantellerite includes Amphibole, Feldspar, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Syenite vs Pantellerite, 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, Pantellerite is available in dark greenish - grey colors. Appearance of Syenite is Banded and Foilated and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Syenite vs Pantellerite. The hardness of Syenite is 5.5-6 and that of Pantellerite is 6-7. The types of Syenite are Shonkinite whereas types of Pantellerite are Pantelleritic Ignimbrite. 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 Pantellerite is unknown. The specific heat capacity of Syenite is 0.92 kJ/Kg K and that of Pantellerite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Syenite is heat resistant, impact resistant, wear resistant whereas Pantellerite is heat resistant.
