Definition
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.
Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature

Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite 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.

All about Serpentinite and Blueschist Properties
Know all about Serpentinite and Blueschist properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite and Blueschist belong to Metamorphic Rocks.Texture of Serpentinite is Earthy whereas that of Blueschist is Foliated. Serpentinite appears Rough and Dull and Blueschist appears Dull and Banded. The luster of Serpentinite is waxy and dull while that of Blueschist is dull. Serpentinite is available in black, brown, green, grey, white colors whereas Blueschist is available in blue, bluish - grey, purple, shades of blue colors. The commercial uses of Serpentinite are commemorative tablets, creating artwork and that of Blueschist are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
