5.1 Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Pseudotachylite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
