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.
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

More about Jadeitite and Blueschist
Here you can know more about Jadeitite and Blueschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Blueschist consists of mineral content and compound content. The mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Blueschist includes Albite, Chlorite, Epidote, Garnet, Glaucophane, Lawsonite, Muscovite or Illite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Jadeitite vs Blueschist, 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, Blueschist is available in blue, bluish - grey, purple, shades of blue colors. Appearance of Jadeitite is Rough and Dull and that of Blueschist is Dull and Banded. Properties of rock is another aspect for Jadeitite vs Blueschist. The hardness of Jadeitite is 3-5 and that of Blueschist is 3.5-4. The types of Jadeitite are Metamorphic rock whereas types of Blueschist are Metamorphic 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 Blueschist is white to grey. The specific heat capacity of Jadeitite is 0.95 kJ/Kg K and that of Blueschist 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 Blueschist is impact resistant, pressure resistant.
