Archaeological Significance
Formation
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.
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.

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