Definition
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

Formation
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.
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.

Arkose 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. Arkose vs Carbonatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Arkose and Properties of Carbonatite. Learn more about Arkose vs Carbonatite in the next section. The interior uses of Arkose include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Carbonatite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Arkose and Carbonatite, they have various applications in construction industry. The uses of Arkose in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar 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 Arkose and Carbonatite
Here you can know more about Arkose and Carbonatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Arkose and Carbonatite consists of mineral content and compound content. The mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz 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 Arkose vs Carbonatite, the texture, color and appearance plays an important role in determining the type of rock. Arkose is available in reddish brown colors whereas, Carbonatite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Arkose is Rough and Dull and that of Carbonatite is Dull, Banded and Foilated. Properties of rock is another aspect for Arkose vs Carbonatite. The hardness of Arkose is 6-7 and that of Carbonatite is 3. The types of Arkose are Not Available 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 Arkose and Carbonatite is white.
