In this work we present ASCA spatially resolved spectra for the cooling flow cluster Abell 496. We find a mild abundance gradient and a more obvious temperature gradient: within the central 3 arcminutes, abundances are 0.48 solar and the temperature is 3.38 keV; in the outer regions the abundance is 0.35 and the temperature is 4.22 keV; the outer values differ from the central values at >90% confidence levels. We also compare the abundance distribution to galaxy morphological distributions in A496 to determine which galaxy population contributes most to ICM enrichment; analogous relations for Virgo and Coma are also described.
