It is shown on the basis of analysis of the Delaunay simplices of the atomic structure of the Cu64Zr36 metallic glass in the process of plastic deformation that the density distribution of the basic structure units of tetrahedrons and quartoctahedrons in the system is practically unchanging. The elementary acts of plastic deformation are reduced to restructuring of local atomic configurations of tetrahedrons into quartoctahedrons and, vice versa, quartoctahedrons into tetrahedrons, while preserving the quantitative relation between the structural units.
