5 Formation

5.1 Formation

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

Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.
