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.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
