5.1 Formation

Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

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