Formation

Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

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.
