   We propose to observe two coronal X-ray sources identified with super-
   metal-rich (SMR) late-type stars, in order to search for any evidence
   of high metal abundances in the emitting plasma. The two targets have
   been selected in order to be bright enough to get relatively high
   signal-to-noise SIS spectra with reasonable exposure times. The
   observations of these stars, whose photospheric abundances are well
   determined trough high-resolution optical spectroscopy, will help to
   test current hypotheses about the link between photospheric and coronal
   plasma abundances. In particular, the proposed observations will
   provide an unprecedented opportunity to test whether the SMR stars are
   affected by the "Metal Abundance Deficiency" syndrome, discovered in
   other coronal sources observed by ASCA.
