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.
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

More about Jadeitite and Dunite
Here you can know more about Jadeitite and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Dunite consists of mineral content and compound content. The mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Jadeitite vs Dunite, the texture, color and appearance plays an important role in determining the type of rock. Jadeitite is available in black, brown, colourless, green, grey, white colors whereas, Dunite is available in dark greenish - grey colors. Appearance of Jadeitite is Rough and Dull and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Jadeitite vs Dunite. The hardness of Jadeitite is 3-5 and that of Dunite is 3.5-4. The types of Jadeitite are Not Available whereas types of Dunite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jadeitite and Dunite is white, greenish white or grey. The specific heat capacity of Jadeitite is 0.95 kJ/Kg K and that of Dunite is 1.25 kJ/Kg K.
