  The results of hybrid simulation of low-beta supercritical quasi-parallel
shocks in high metallicity plasma are presented. The structure of upstream and
downstream turbulence is addressed and velocities of the corresponding
scattering centers are derived. It is shown that independently of their
chemical composition the shocks experience self-reformation process. However,
the period of self-reformation as well as the wave spectrum is greatly affected
by the presence of substantial admixture of weakly charged heavy ions. Also the
downstream magnetic field amplification is stronger for the high metallicity
case.
