Definition
Jadeitite is a metamorphic rock usually found in blueschist grade metamorphic terrains
Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.

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.
Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, and are erupted rapidly and violently.

More about Jadeitite and Kimberlite
Here you can know more about Jadeitite and Kimberlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Kimberlite consists of mineral content and compound content. The mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Kimberlite includes Garnet, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Jadeitite vs Kimberlite, 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, Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Jadeitite is Rough and Dull and that of Kimberlite is Dull and Banded. Properties of rock is another aspect for Jadeitite vs Kimberlite. The hardness of Jadeitite is 3-5 and that of Kimberlite is 6-7. The types of Jadeitite are Metamorphic rock whereas types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jadeitite and Kimberlite is white, greenish white or grey. The specific heat capacity of Jadeitite is 0.95 kJ/Kg K and that of Kimberlite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Jadeitite is heat resistant, water resistant whereas Kimberlite is heat resistant, impact resistant.
