Formation

Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

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.
