1.1 Definition

Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters

Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism

5 Formation

5.1 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.

Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
