Resumen

We present preliminary iron abundances and α element (Ca, Mg) abundance ratios for a sample of 22 Red Giant Branch (RGB) Stars in the Sagittarius 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 presented by [2].
