Flint and Carbonatite
Definition
Definition
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

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