Definition
Jadeitite is a metamorphic rock usually found in blueschist grade metamorphic terrains
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

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.
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

More about Jadeitite and Adakite
Here you can know more about Jadeitite and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Adakite consists of mineral content and compound content. The mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Adakite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Jadeitite vs Adakite, 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, Adakite is available in black, brown, light to dark grey colors. Appearance of Jadeitite is Rough and Dull and that of Adakite is Dull and Soft. Properties of rock is another aspect for Jadeitite vs Adakite. The hardness of Jadeitite is 3-5 and that of Adakite is 3-4. The types of Jadeitite are Metamorphic rock whereas types of Adakite are Intermediate volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jadeitite is white, greenish white or grey while that of Adakite is bluish black. The specific heat capacity of Jadeitite is 0.95 kJ/Kg K and that of Adakite is 0.84 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 Adakite is heat resistant, pressure resistant, wear resistant.
