Formation

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

Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.
