We propose to observe two lowactivity supermetalrich (SMR) latetype stars,in order to determine the individual element abundances and the plasma emission measure distribution vs. temperature, from the joint analysis of EPIC and RGS spectra. The XMM observations of these peculiar targets will help to testcurrent hypotheses about the dependence of the element fractionationmechanism(s) in corona on the stellar magnetic activity level.
