5.1 Formation
Chert forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The chert formation can be either of chemical or biological origin.
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

Chert vs Carbonatite 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 Chert and Carbonatite Reserves. Chert is a hard, dark, opaque sedimentary rock which is composed of silica with an amorphous fine-grained texture. Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals. 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 Chert vs Carbonatite information and Chert vs Carbonatite characteristics in the upcoming sections.

Chert vs Carbonatite 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. Chert vs Carbonatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chert and Properties of Carbonatite. Learn more about Chert vs Carbonatite in the next section. The interior uses of Chert include Decorative aggregates and Homes whereas the interior uses of Carbonatite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Chert and Carbonatite, they have various applications in construction industry. The uses of Chert in construction industry include Arrowheads, Construction aggregate, Cutting tool, Spear points and that of Carbonatite 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, Unknown, Unknown.

More about Chert and Carbonatite

Here you can know more about Chert and Carbonatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chert and Carbonatite consists of mineral content and compound content. The mineral content of Chert includes Quartz, Silicon and mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Chert vs Carbonatite, the texture, color and appearance plays an important role in determining the type of rock. Chert is available in black, brown, green, grey, red, white colors whereas, Carbonatite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Chert is Glassy or Pearly and that of Carbonatite is Dull, Banded and Foilated. Properties of rock is another aspect for Chert vs Carbonatite. The hardness of Chert is 6.5-7 and that of Carbonatite is 3. The types of Chert are Flint, Jasper, Radiolarite, Common Chert, Chalcedony, Agate, Onyx, Opal, Magadi-type Chert, Porcelanite, Siliceous Sinter whereas types of Carbonatite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chert and Carbonatite is white.
