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.

Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.
