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.

Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
