Archaeological Significance
Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.
