Resumen

In the NW part of the province of Salamanca (Spain) many pegmatites occur. Some of them correspond to Li-bearing pegmatites, but other pegmatitic types are also important. In this paper tourmalines from some of this pegmatitic bodies and their tourmalinized host-rock are examined in terms of their chemistry and conditions of formation. According to their chemistry, they belong to the schorl-dravite series. Substitutions towards alkali-free or proton deficient members are observed. The chemical variations between the studied tourmalines could indicate a different origin for their associate rocks.
