Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
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.
