\abstract{En este trabajo analizamos las propiedades químicas de $\sim$ 300 estrellas 
gigantes rojas pertenecientes a 15 campos estelares de la Nube Menor de 
Magallanes (NmM). Las metalicidades fueron determinadas a partir de los anchos equivalentes
de las líneas del Triplete del CaII, medidos en espectros obtenidos con el 
instrumento FORS2 del Very Large Telescope ubicado en Paranal (Chile). Sumamos a esta muestra otras $\sim$ 350 estrellas
gigantes rojas investigadas previamente por nuestro grupo aplicando la misma técnica. 
Usando esta muestra extendida, analizamos y discutimos la distribución de metalicidades
 y la posible existencia de un gradiente de metalicidad entre las estrellas del campo de
 la NmM. Comparamos, además, las propiedades químicas inferidas con las correspondientes a 30 
cúmulos estelares de la NmM, cuyas metalicidades han sido determinadas en una escala homogénea
