Definition
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals
Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase

Formation
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.
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

Carbonatite vs Amphibolite 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. Carbonatite vs Amphibolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Carbonatite and Properties of Amphibolite. Learn more about Carbonatite vs Amphibolite in the next section. The interior uses of Carbonatite include Decorative aggregates and Interior decoration whereas the interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Carbonatite and Amphibolite, they have various applications in construction industry. The uses of Carbonatite in construction industry 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 and that of Amphibolite include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone.
More about Carbonatite and Amphibolite
Here you can know more about Carbonatite and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Carbonatite and Amphibolite consists of mineral content and compound content. The mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite and mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite. You can also check out the list of all . When we have to compare Carbonatite vs Amphibolite, the texture, color and appearance plays an important role in determining the type of rock. Carbonatite is available in black, brown, colourless, green, grey, pink, white colors whereas, Amphibolite is available in black, brown, green, grey colors. Appearance of Carbonatite is Dull, Banded and Foilated and that of Amphibolite is Foliated. Properties of rock is another aspect for Carbonatite vs Amphibolite. The hardness of Carbonatite is 3 and that of Amphibolite is 6-7. The types of Carbonatite are Not Available whereas types of Amphibolite are Hornblendite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Carbonatite is white while that of Amphibolite is white to grey. The specific heat capacity of Carbonatite is Not Available and that of Amphibolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Carbonatite is heat resistant, pressure resistant, water resistant whereas Amphibolite is heat resistant, pressure resistant, wear resistant.
