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

Granulite vs Phonolite 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 Phonolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Phonolite. Learn more about Granulite vs Phonolite 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 Phonolite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Granulite and Phonolite, 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 Phonolite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics.
More about Granulite and Phonolite
Here you can know more about Granulite and Phonolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Phonolite 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 Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Phonolite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Phonolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Granulite is Veined or Pebbled and that of Phonolite is Banded and Foilated. Properties of rock is another aspect for Granulite vs Phonolite. The hardness of Granulite is 6-7 and that of Phonolite is 5.5-6. The types of Granulite are Metamorphic rock whereas types of Phonolite are Kenyte. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Phonolite is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Phonolite is 0.84 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 Phonolite is heat resistant, impact resistant, wear resistant.
