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.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
