Definition
Granophyre is a type of granitic rock which consists of intergrown feldspar and quartz crystals in a medium to fine grained groundmass
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals

Formation
Granophyre 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.

Granophyre 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. Granophyre vs Syenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granophyre and Properties of Syenite. Learn more about Granophyre vs Syenite in the next section. The interior uses of Granophyre include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, 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 Granophyre and Syenite, they have various applications in construction industry. The uses of Granophyre in construction industry include As dimension stone 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 Granophyre and Syenite
Here you can know more about Granophyre and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granophyre and Syenite consists of mineral content and compound content. The mineral content of Granophyre includes Hornblade, Orthoclase, 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 Igneous Rocks. When we have to compare Granophyre vs Syenite, the texture, color and appearance plays an important role in determining the type of rock. Granophyre is available in black, grey, orange, pink, white colors whereas, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Granophyre is Veined or Pebbled and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Granophyre vs Syenite. The hardness of Granophyre is 6-7 and that of Syenite is 5.5-6. The types of Granophyre 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 Granophyre and Syenite is white. The specific heat capacity of Granophyre 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.Granophyre is heat resistant, wear resistant whereas Syenite is heat resistant, impact resistant, wear resistant.
