Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
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.

Charnockite 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. Charnockite vs Foidolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Charnockite and Properties of Foidolite. Learn more about Charnockite vs Foidolite in the next section. The interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Foidolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Charnockite and Foidolite, they have various applications in construction industry. The uses of Charnockite in construction industry include As dimension stone and that of Foidolite include As dimension stone, Cement manufacture, For road aggregate.
More about Charnockite and Foidolite
Here you can know more about Charnockite and Foidolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Foidolite consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz and mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Foidolite, the texture, color and appearance plays an important role in determining the type of rock.
