Definition
Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

Formation
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
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.

Diabase 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. Diabase vs Carbonatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diabase and Properties of Carbonatite. Learn more about Diabase vs Carbonatite in the next section. The interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens whereas the interior uses of Carbonatite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Diabase and Carbonatite, they have various applications in construction industry. The uses of Diabase in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate 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.
More about Diabase and Carbonatite
Here you can know more about Diabase and Carbonatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Carbonatite consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Diabase vs Carbonatite, the texture, color and appearance plays an important role in determining the type of rock. Diabase is available in dark grey to black colors whereas, Carbonatite is available in black, brown, green, grey, pink, white colors. Appearance of Diabase is Vesicular and that of Carbonatite is Dull, Banded and Foilated. Properties of rock is another aspect for Diabase vs Carbonatite. The hardness of Diabase is 7 and that of Carbonatite is 3. The types of Diabase are Dolerite whereas types of Carbonatite are Carbonatite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diabase is black while that of Carbonatite is white. The specific heat capacity of Diabase is 0.84 kJ/Kg K and that of Carbonatite is 0.51 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diabase is heat resistant, impact resistant, pressure resistant, wear resistant whereas Carbonatite is heat resistant, pressure resistant, water resistant.
