5 Formation

5.1 Formation

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.

Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
