Formation

Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.

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