Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature
From French schiste, Greek skhistos i.e. split

Archaeological Significance
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.
