Formation
Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.
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.

Gritstone 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. Gritstone vs Carbonatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Gritstone and Properties of Carbonatite. Learn more about Gritstone vs Carbonatite in the next section. The interior uses of Gritstone include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Carbonatite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Gritstone and Carbonatite, they have various applications in construction industry. The uses of Gritstone in construction industry include Construction aggregate, Roadstone 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 Gritstone and Carbonatite
Here you can know more about Gritstone and Carbonatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gritstone and Carbonatite consists of mineral content and compound content. The mineral content of Gritstone includes Calcite, 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 Gritstone vs Carbonatite, the texture, color and appearance plays an important role in determining the type of rock. Gritstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Carbonatite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Gritstone is Layered and Foliated and that of Carbonatite is Dull, Banded and Foilated. Properties of rock is another aspect for Gritstone vs Carbonatite. The hardness of Gritstone is 6-7 and that of Carbonatite is 3. The types of Gritstone 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 Gritstone and Carbonatite is white. The specific heat capacity of Gritstone is 0.92 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.Gritstone is heat resistant, impact resistant, pressure resistant whereas Carbonatite is heat resistant, pressure resistant, water resistant.
