Foidolite vs Dolomite


Definition

Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

Formation

Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.   
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 vs Foidolite 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 Dolomite and Foidolite Reserves. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%. 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 Dolomite vs Foidolite information and Dolomite vs Foidolite characteristics in the upcoming sections.

Dolomite 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. Dolomite vs Foidolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Foidolite. Learn more about Dolomite vs Foidolite in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Foidolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Dolomite and Foidolite, they have various applications in construction industry. The uses of Dolomite in construction industry 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 and that of Foidolite include As dimension stone, Cement manufacture, For road aggregate.

More about Dolomite and Foidolite

Here you can know more about Dolomite and Foidolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Foidolite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Foidolite, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas, Foidolite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Dolomite is Glassy or Pearly and that of Foidolite is Dull. Properties of rock is another aspect for Dolomite vs Foidolite. The hardness of Dolomite is 3.5-4 and that of Foidolite is 1.5. The types of Dolomite are Boninite and Jasperoid whereas types of Foidolite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dolomite and Foidolite is white. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Foidolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Dolomite is heat resistant, pressure resistant, wear resistant whereas Foidolite is heat resistant, wear resistant.
