Definition
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Archaeological Significance
Formation
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

Syenite vs Quartzite 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 Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Syenite and Properties of Quartzite. Learn more about Syenite vs Quartzite in the next section. The interior uses of Syenite include Flooring, Homes, Hotels and Interior decoration whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Syenite and Quartzite, 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 Quartzite include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone.
More about Syenite and Quartzite
Here you can know more about Syenite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Syenite and Quartzite 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 Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Syenite vs Quartzite, 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, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Syenite is Banded and Foilated and that of Quartzite is Lustrous. Properties of rock is another aspect for Syenite vs Quartzite. The hardness of Syenite is 5.5-6 and that of Quartzite is 6-7. The types of Syenite are Shonkinite whereas types of Quartzite are Orthoquartzite and Metaquartzite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Syenite and Quartzite is white. The specific heat capacity of Syenite is 0.92 kJ/Kg K and that of Quartzite is 0.75 kJ/Kg K. 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 Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
