Formation

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

Foidolite vs Charnockite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Foidolite and Charnockite Reserves. Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%. Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Foidolite vs Charnockite information and Foidolite vs Charnockite characteristics in the upcoming sections.

Foidolite vs Charnockite 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 Charnockite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Foidolite and Properties of Charnockite. Learn more about Foidolite vs Charnockite in the next section. The interior uses of Foidolite include Decorative aggregates and Interior decoration whereas the interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Foidolite and Charnockite, 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 Charnockite include As dimension stone.

More about Foidolite and Charnockite

Here you can know more about Foidolite and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Foidolite and Charnockite consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene and mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Foidolite vs Charnockite, the texture, color and appearance plays an important role in determining the type of rock. Foidolite is available in black, brown, colourless, green, grey, pink, white colors whereas, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Foidolite is Dull and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Foidolite vs Charnockite. The hardness of Foidolite is 1.5 and that of Charnockite is 6-7. The types of Foidolite are Not Available whereas types of Charnockite are Enderbite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Foidolite and Charnockite is white. The specific heat capacity of Foidolite is Not Available and that of Charnockite is Not Available. 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 Charnockite is heat resistant, wear resistant.
