We present metallicities for 487 red giants in the Carina dwarf spheroidal ( dSph ) galaxy that were obtained from FLAMES low-resolution Ca triplet ( CaT ) spectroscopy .
We find a mean [ Fe/H ] of -1.91 dex with an intrinsic dispersion of 0.25 dex , whereas the full spread in metallicities is at least one dex .
The analysis of the radial distribution of metallicities reveals that an excess of metal poor stars resides in a region of larger axis distances .
These results can constrain evolutionary models and are discussed in the context of chemical evolution in the Carina dSph .
