Abstract We compare the metal abundance distribution in the distant cool-core
cluster WARPJ1415.1+3612 at z=1.03 (Santos et al. 2012) to that of a sample
of local clusters. We find that the metal distribution in
WARPJ1415.1+3612, as measured by Chandra, is comparable to that of the
optical light of the associated BCG observed with HST. This is at
variance with local systems where the metal distribution is
significantly broader than the optical light. We discuss the
implications for cluster formation and evolution models of this
important result.
