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