Definition
Ijolite is an intrusive igneous rock which is composed mainly of nepheline and an alkali pyroxene, usually aegirine-augite
Jadeitite is a metamorphic rock usually found in blueschist grade metamorphic terrains

Formation
Ijolite 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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Ijolite and Jadeitite
Here you can know more about Ijolite and Jadeitite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ijolite and Jadeitite consists of mineral content and compound content. The mineral content of Ijolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite and mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Ijolite vs Jadeitite, the texture, color and appearance plays an important role in determining the type of rock. Ijolite is available in brown, buff, cream, green, grey, pink, white colors whereas, Jadeitite is available in black, brown, green, grey, white colors. Appearance of Ijolite is Banded and Foilated and that of Jadeitite is Rough and Dull. Properties of rock is another aspect for Ijolite vs Jadeitite. The hardness of Ijolite is 5.5-6 and that of Jadeitite is 3-5. The types of Ijolite are Alkaline rock whereas types of Jadeitite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Ijolite is white while that of Jadeitite is white, greenish white or grey. The specific heat capacity of Ijolite is 0.84 kJ/Kg K and that of Jadeitite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Ijolite is heat resistant, impact resistant, wear resistant whereas Jadeitite is heat resistant, water resistant.
