Abstract
Recent ASCA results on the distributions of METALLICITY and temperature are presented. Following the discovery of a large-scale gradient in the iron abundance in AWM7, Perseus cluster and A4059 also show very similar features. The close distribution of iron mass density with that of galaxies suggests that the metals are not significantly mixed or settled in the intracluster medium. The north-east and south regions of the Virgo cluster have been mapped with ASCA by more than 30 pointings. The energy spectrum shows a remarkable hardening in the region between M87 and M49. This feature is possibly related with the falling of M49 subcluster into the main M87 cluster.
