dc.descriptionWe present preliminary iron abundances and $α$ element (Ca, Mg) abundance ratios for a sample of 22 Red Giant Branch (RGB) Stars in the Sagittarius dwarf spheroidal galaxy (Sgr), selected near the RGB-Tip. The sample is representative of the Sgr dominant population. The mean iron abundance is [Fe/H]=-0.49. The $α$ element abundance ratios are slightly subsolar, in agreement with the results recently prensented by Bonifacio et al.(2004, A&A, 414, 503).
