Formation

Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

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