Definition
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
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.

Limestone 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. Limestone vs Carbonatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Carbonatite. Learn more about Limestone vs Carbonatite in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Carbonatite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Limestone and Carbonatite, they have various applications in construction industry.

More about Limestone and Carbonatite
Here you can know more about Limestone and Carbonatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Carbonatite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt 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 Limestone vs Carbonatite, the texture, color and appearance plays an important role in determining the type of rock. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas, Carbonatite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Limestone is Rough and Banded and that of Carbonatite is Dull, Banded and Foilated. Properties of rock is another aspect for Limestone vs Carbonatite. The hardness of Limestone is 3-4 and that of Carbonatite is 3. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa 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 Limestone and Carbonatite is white. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Carbonatite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Limestone is pressure resistant whereas Carbonatite is heat resistant, pressure resistant, water resistant.
