Formation

Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

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