Formation

Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

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