Definition
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%
Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone
Discoverer
Unknown
Alexander von Humboldt
Etymology
From the mineral feldspathoid which is the main content of rock
From Italian granito, which means grained rock, from grano grain, and from Latin granum

Formation
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.
Granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks

Foidolite vs Granite 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. Foidolite vs Granite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Foidolite and Properties of Granite. Learn more about Foidolite vs Granite in the next section. The interior uses of Foidolite include Decorative aggregates and Interior decoration whereas the interior uses of Granite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Foidolite and Granite, they have various applications in construction industry. The uses of Foidolite in construction industry include As dimension stone, Cement manufacture, For road aggregate and that of Granite include As dimension stone.
More about Foidolite and Granite
Here you can know more about Foidolite and Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Foidolite and Granite consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene and mineral content of Granite 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 Foidolite vs Granite, the texture, color and appearance plays an important role in determining the type of rock. Foidolite is available in black, brown, green, grey, pink, white colors whereas, Granite is available in black, grey, orange, pink, white colors. Appearance of Foidolite is Dull and that of Granite is Veined or Pebbled. Properties of rock is another aspect for Foidolite vs Granite. The hardness of Foidolite is 1.5 and that of Granite is 6-7. The types of Foidolite are Igneous rock whereas types of Granite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite, Hybrid Granite, Granodiorite and Alkali Feldspar Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Foidolite and Granite is white. The specific heat capacity of Foidolite is 0.79 kJ/Kg K and that of Granite 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.Foidolite is heat resistant, wear resistant whereas Granite is heat resistant, wear resistant.
