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.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Foidolite vs Dolomite 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 Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Foidolite and Properties of Dolomite. Learn more about Foidolite vs Dolomite in the next section. The interior uses of Foidolite include Decorative aggregates and Interior decoration whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Foidolite and Dolomite, 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 Dolomite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics, Serves as an oil and gas reservoir rock.
More about Foidolite and Dolomite
Here you can know more about Foidolite and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Foidolite and Dolomite consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene and mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Foidolite vs Dolomite, 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, Dolomite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Foidolite is Dull and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Foidolite vs Dolomite. The hardness of Foidolite is 1.5 and that of Dolomite is 3.5-4. The types of Foidolite are Not Available whereas types of Dolomite are Boninite and Jasperoid. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Foidolite and Dolomite is white. The specific heat capacity of Foidolite is Not Available and that of Dolomite is 0.92 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 Dolomite is heat resistant, pressure resistant, wear resistant.
