Formation
Icelandite 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 Icelandite and Jadeitite
Here you can know more about Icelandite and Jadeitite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Icelandite and Jadeitite consists of mineral content and compound content. The mineral content of Icelandite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon 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 Icelandite vs Jadeitite, the texture, color and appearance plays an important role in determining the type of rock. Icelandite is available in bluish - grey, grey, pink, yellow colors whereas, Jadeitite is available in black, brown, green, grey, white colors. Appearance of Icelandite is Dull and Soft and that of Jadeitite is Rough and Dull. Properties of rock is another aspect for Icelandite vs Jadeitite. The hardness of Icelandite is 7 and that of Jadeitite is 3-5. The types of Icelandite are Intermediate volcanic 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 Icelandite is white while that of Jadeitite is white, greenish white or grey. The specific heat capacity of Icelandite is 2.39 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.Icelandite is heat resistant, pressure resistant, scratch resistant, wear resistant whereas Jadeitite is heat resistant, water resistant.
