Title: Chemical Evolution of the Small Magellanic Cloud. Comparison of the chemical properties 
of clusters and their surrounding fields.

Abstract:
Our group has been studying for several years star clusters and field stars of the Small 
Magellanic Cloud (SMC), using the  FORS2 instrument on the VLT (Paranal, Chile). We 
have derived metallicities from CaT lines and ages from both the δV parameter and (V,V-I)  
color-magnitude diagrams. We have studied 30 star clusters and approximately 700 field stars 
surrounding these clusters. We have analyzed and compared the chemical properties of those 
clusters and their surrounding field stars. We found evidence for possible differences between 
the chemical evolution histories of these two different  SMC stellar populations.
