Abstrakt: We investigate efficiency and time dependence of metal enrichment processes in the intra-cluster medium (ICM). In this presentation, we concentrate on the effects of galactic winds. The mass loss rates due to galactic winds are calculated with a special algorithm, which takes into account cosmic rays and magnetic fields. This algorithm is embedded in a combined N-body/hydrodynamic code which calculates the dynamics and evolution of a galaxy cluster. We give metallicity maps, which show the metal distribution in the ICM caused by galactic winds of quiet, i.e., non-starburst, disk galaxies. Œ 2005 COSPAR. Published by Elsevier Ltd.
