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.
Foidolites 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.

Granulite vs Foidolite 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 Foidolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Foidolite. Learn more about Granulite vs Foidolite 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 Foidolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Granulite and Foidolite, 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 Foidolite include As dimension stone, Cement manufacture, For road aggregate.
More about Granulite and Foidolite
Here you can know more about Granulite and Foidolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Foidolite 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 Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Foidolite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Foidolite is available in black, brown, green, grey, pink, white colors. Appearance of Granulite is Veined or Pebbled and that of Foidolite is Dull. Properties of rock is another aspect for Granulite vs Foidolite. The hardness of Granulite is 6-7 and that of Foidolite is 1.5. The types of Granulite are Metamorphic rock whereas types of Foidolite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Foidolite is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Foidolite is 0.79 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 Foidolite is heat resistant, wear resistant.
