Definition
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

Formation
Norite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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.

More about Norite and Carbonatite
Here you can know more about Norite and Carbonatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Carbonatite consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene 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 Norite vs Carbonatite, the texture, color and appearance plays an important role in determining the type of rock. Norite is available in dark grey to black colors whereas, Carbonatite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Norite is Veined and Shiny and that of Carbonatite is Dull, Banded and Foilated. Properties of rock is another aspect for Norite vs Carbonatite. The hardness of Norite is 7 and that of Carbonatite is 3. The types of Norite 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 Norite is black while that of Carbonatite is white. The specific heat capacity of Norite is Not Available 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.Norite is impact resistant, pressure resistant, wear resistant whereas Carbonatite is heat resistant, pressure resistant, water resistant.
