Formation
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Granulite vs Syenite 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. Granulite vs Syenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Syenite. Learn more about Granulite vs Syenite in the next section. The interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Syenite include Flooring, Homes, Hotels and Interior decoration. Due to some exceptional properties of Granulite and Syenite, they have various applications in construction industry. The uses of Granulite in construction industry include As dimension stone, Building houses or walls and that of Syenite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Granulite and Syenite
Here you can know more about Granulite and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Syenite consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, 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 Metamorphic Rocks. When we have to compare Granulite vs Syenite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Granulite is Veined or Pebbled and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Granulite vs Syenite. The hardness of Granulite is 6-7 and that of Syenite is 5.5-6. The types of Granulite are Not Available 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 Granulite and Syenite is white. The specific heat capacity of Granulite is 0.14 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.Granulite is heat resistant, wear resistant whereas Syenite is heat resistant, impact resistant, wear resistant.
