The globular clusters associated with the giant elliptical galaxy M87 are, on average, substantially more metal-rich than the average cluster in the Milky Way (although the full range of observed metallicities may not be very different). A substantial fraction of the M87 clusters appears to be more metal-rich than the most metal-rich known globular clusters in the Galaxy. There is a suggestion that cluster metallicity depends on luminosity, with fainter clusters being more metal-poor; this relationship may be the manifestation of a self-enrichment process, which is most important in extremely massive clusters. 26 references.
