Definition
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

Formation
Tachylite 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 Tachylite and Carbonatite
Here you can know more about Tachylite and Carbonatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Carbonatite consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine 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 Tachylite vs Carbonatite, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Carbonatite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Tachylite is Glassy and that of Carbonatite is Dull, Banded and Foilated. Properties of rock is another aspect for Tachylite vs Carbonatite. The hardness of Tachylite is 5.5 and that of Carbonatite is 3. The types of Tachylite 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 Tachylite is vermilion while that of Carbonatite is white. The specific heat capacity of Tachylite is 0.56 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.Tachylite is heat resistant, impact resistant, wear resistant whereas Carbonatite is heat resistant, pressure resistant, water resistant.
